IHDP Members y-DNA Results and Analysis

When you go to the relevant haplogroup Results Pages you may notice any of the following icons:

ICONS of Result File Types For Downloading - Examples Only
MS Excell File	CSV - Text File	HTML File	Acrobat PDF File	Text File
Note: the icons depicted here are examples, they have no files associated with them. Further down on this page are the complete results of the members of IHDP. The icons above indicate an IHDP results table in that file type is available to download to your computer or to view the file. These files are extracted and formatted from MS Acess and are sorted to nearest matches. The Excell Spreadsheet for instance will have some formatting. Important: When you open an Excell (XLS) file in your Browser a copy of the open fill is stored in your temp/cache folders. The next time you open the Spreadsheet you should Reload/Refresh the the file when open in your browser.

Accessing Results - Colour Coding - Explained

In the Excell Spreadsheet results table, we have used various colour coding in the columns to indicate Fast Mutating Columns and also Blue Markers for deep ancestry testing and research.

Red Marker Columns - indicate Fast Mutating DYS Markers - these can and should be used to determine relatedness between close matching results.

Blue columns reflect the ten markers used in the appendices of Bryan Sykes book "Blood of the Isles" - Bantam press, London*. The Blue columns are useful guides for deep ancestry study.

Haplogroup Columns in the Results Spreadsheet with R1b1 should be assumed to be Predicted, anything else is SNP Conformed for example R1b1, R1b1b2, R1b1b2e, R1b1b2g, R1b1b2 etc.

Complete IHDP yDNA Membership Results Files For Downloading - 3,500 + Irish Results

Here is the complete set of IHDP membership results merged and sorted with the Trinity results. In the Excell file below there is an autofilter on the header to enable turning/on/off columns and carrying out queries. The CSV (comma-delimited) text file was generated by Excell and can be opened in Excell or any text editor to be used for further research. The text file is a "space" delimited file and useful also for further research purposes.

There are four new fields to the far right in the excell sheet below, Regional (Provincial), County, Historical and Reference. Note the County location is for the historical distribution of the surname, some surnames are widely distributed but the county location is the historical dynastic surname location. The Counties are abbriviated with the firt and last letter of the county DN = Down, Dublin = D, some counties cannot be represented in this way, Waterfrod = WD and Wexford = WX.

IMPORTANT: No matter what Web-Browser you use, there are standard conventions when opening linked files. Always Right-Click on an icon - if you click ONCE you will open the file in your browser. Right-Click on any of the above icons and you can choose to, OPEN Link, Save As Target (to your Hard-drive) or to PRINT. Caution: You may view, save or print the yDNA results or other information on this site. Common courtesy requires permission to use the yDNA data here for anything other than personal use and privacy laws may govern its use. If you do use the yDNA data please ensure that permission is sought and obtained for its use from the individual members concerned. When information is being used and permission obtained please acknowledge this source.

*The results associated with the Sykes book are available as a downloadable PDF file from the following website: Blood of the Isles. For information on the markers used by Prof Bradley at Trinity College in the R1b1b2e (R1b1c7) study check IHDP's own information here Focus on R1b1b2e (R1b1c7) .

Important Security Item: Only a persons Kit number and Surname will be displayed, this is to protect members privacy. If you remove yourself from the IHDP project on the fTDNA website please notify us. Especially if you want your details/results retained in the IHDP Database let us know. If not we will remove it as the data is not our property it is the property of the individual members.

Get the Most Out of Your Results

The IHDP results files can be used for further research. The MS Excel Spreadsheet Results tables can be used for various analysis. The Text file is a "Tabbed delimited" text file and can be used to check for the following:

Haplogroup Prediction

Whit Athey's excellant Haplogroup Predictor, located here: Whit Athey's Haplogroup Predictor you can upload your tabbed delimited results and check your most likely Haplogroup. This is very useful if your Prediction is not clear or unknown. When using these tabbed delimited files, ensure you remove, the Kit, Surname, and Haplogroup columns, as well as the empty rows (usually 464e, f, g) and any other columns that are present in the IHDP Text files and not needed.

Identifing and Interpreting Multi-copy and Fast mutating markers

Fast moving markers are shown as red columns in all IHDP generated tables.

Fast Moving markers:
DYS 385a, b
DYS 439
DYS 458
DYS 449
DYS 464a, b, c, d
DYS 456
DYS 576
DYS 570
CDYa, b

Multi-Copy Markers
385a, b
459a, b
464a, b, c, d, e, f, g
YCA II a, b
CDY a, b
395S1a, b
413a, 413b

Interpreting the results for a multi-copy marker

Multi-Copy markers are reported in ascending order, this is crucial and it can lead to a misintrepretation of the results. The following explaination uses DYS 464 a-g.

For example, here are some results for DYS464:
11 11 14 16
12 14 15 16

Since the results are reported in ascending order for multi-copy markers, this must be taken into account when comparing the results of the markers between individuals.

For example, consider the following results:

Example 1: 15 15 17 17
Example 2: 13 13 15 17

At a glance, you may see 3 differences, but there are really only 2. To correctly interpret the results for this multi-copy marker, the results that match are not counted as differences. The 15 in the first example above matches a 15 in the second example, so the 15 is not counted as a difference, even though the two 15's do not line up in the display of the results. A 17 from the first example matches the 17 in the second example. The two 13's in the second example do not have a match in the first example, so in comparing these two results, we find 2 differences.

Measuring Genetic Distance

Dean McGee's invaluable Research Tool for Genetic Distance measurement is located here: McGee's yDNA Distance Utility this is a very good utility to measure genetic distance matching, using generations and years. It is quite complex to use for the first few times but is well worth the effort. IHDP would recommend you download the Excell File (XLS) and Export the rows you want as CSV Text files (Comma delimited text files0.

Top Nine Unique Haplotypes in the Extended IHDP Membership

The following table shows the top nine unique haplotypes in the IHDP database. Also displayed to the left of the table is the breakdown of the total by region/province.

The above percentages are based on the full IHDP membership of 2,260.. This seems to confirm general Hg findings elsewhere. It should be borne in mind, that IHDP has few members from the more common surnames in Ireland. Surnames like, O'Brien, Murphy, Kavanagh, Callaghan, Butler, Burke. And few representatives of names like O'Kelly, O'Neill, Browne, Kennedy, Smithe et al.
