I recently had a match at MyHeritage that was of pretty good size.<\/p>\n

My DNA Match with Kathleen<\/h2>\n

Kathleen is from Australia. That is good news for me. My father has Hartley and Frazer ancestors. Hartley’s have ancestors from Colonial Massachusetts and more recently from Lancashire, England. If I match on the Hartley side with someone from Australia, that most likely will filter out the Colonial Massachusetts ancestors on my Hartley side and focus on the Lancashire side.<\/p>\n

Here is what my DNA match with Kathleen looks like at MyHeritage:<\/p>\n

Kathleen at AncestryDNA<\/h3>\n

This is how Kathleen and I match at AncestryDNA:
\n\"\"<\/a><\/p>\n

This is quite a difference. Kathleen has gone from 57.2 cM at MyHeritage to 8.2 cM at AncestryDNA. Which one is right?<\/p>\n

I tend to like the AncestryDNA estimates. They use a process that strips away some of the DNA matches that they consider less than significant.<\/p>\n

Kathleen at Gedmatch<\/h3>\n

Gedmatch has a DNA matching number in the middle of AncestryDNA and MyHeritage:<\/p>\n

\"\"<\/a><\/p>\n

However, a common ancestor of 4.6 generations would be an estimated third cousin once removed, similar to the MyHeritage estimate. I think that AncestryDNA’s estimate of 5th to 8th cousin is more accurate.<\/p>\n

Where is the Common Ancestor for Kathleen and Me?<\/h2>\n

Here is one of Kathleen’s ancestors,\u00a0 Emma Walker born 1806 from Haslingdon in orange:<\/p>\n

\"\"<\/a><\/p>\n

I have an ancestor from Goodshaw to the NE of Haslingdon who was Edmund Emmet, born in 1759. These places were fairly close. If Edmund Emmet was our common ancestor, that would be on the order of 5th cousins. I am thinking that the common ancestor would likely be at least another generation out – on the order of 6th cousins. Of course, we don’t know all our ancestors, so there are other possibilities. This is just one of the more likely possibilities.<\/p>\n

Other Considerations<\/h2>\n

Kathleen and I have these common matches according to Gedmatch:<\/p>\n

\"\"<\/a><\/p>\n

Numbers 4-6 include my father’s cousin and his two daughters. Some others have UK or NZ emails. #1 is Kathleen matching with me. The fact that I have my father’s cousin in this comparison insures that my match with Kathleen is along my Hartley grandparent line.<\/p>\n

Summary and Conclusions<\/h2>\n
