If my matches are representative of the wider Family Finder database then there has been over a 50% increase in the size of the database in the last 14 months.
I've also looked at the number of matches I share with my parents and taken stock of the number of matches which don't match either parent.
I share 501 matches with my dad. Of these, 320 were assigned to the paternal side with FTDNA's Family Matching tool. The remaining 181 matches were in common with my dad but did not meet the threshold for Family Matching.
I share 402 matches with my mum. Of these, 276 were assigned to the maternal side with the Family Matching tool. The remaining 126 matches did not meet the threshold for Family Matching.
I therefore have a total of 903 matches (74%) which match my mum or my dad. However, this means that 314 of my 1217 matches (26%) do not appear in the match lists of either of my parents.
All the matches that don't match my parents have a longest segment under 15 cMs. This is the breakdown.
| Longest block | Number |
| 10-14 cMs | 28 |
| 7-9 cMs | 286 |
The last time I did a comparison of parent and child matches I found that 23% of my matches did not match either of my parents.
These matches are either false positives or false negatives but without further investigation it is not possible to tell.
Have you tested both of your parents at Family Tree DNA? What are your statistics?

ReplyDeleteI thought you might be interested to know that I received a response to my e-mail from the blogger. He was very apologetic and has now removed all my articles from his website. I noticed that he's using content from other bloggers in his British section. I've suggested that he remove those posts as well. I've encouraged him to write his own original content instead.
