I am an adoptee. My Father is not named on the Birth certificate though there is a vague description of him on the adoption paperwork. I am not interested at this point in making any contact, this is solely for research purposes, including researching the fact that I am a low DNA match to my adoptive Mother, though we don't know where. My Birth Mother was under 14 when I was conceived and the adoption society suggested my Birth was the result of something that happened at a party. The vague Father description indicates a person of a similar age, rather than an Adult with all the possible ramifications of that.
It has been suggested that as 85% of my matches are unassigned and those that are assigned create anomalies that my Birth Parents are very distantly related. For example my highest DNA match on Ancestry assigned as paternal, is 118cM, but is easily traced as being on my Maternal side.
My highest DNA match is 401cM over 12 segments and is unassigned. There is no link to my Maternal side on that tree so it must be on my Paternal side. The match states that the connection is on their own Maternal side. Looking at the Maternal Grandmother the unusual surname does not crop up in any of my matches trees above 7cM. So the connection must be the Maternal Grandfathers side, some of the surnames going back do crop up in my other matches in the 50-90cM range. If the connection is a Maternal Uncle of my match the connection to the match would be 1st Cousin, but a range of 396-1397 with an average of 866 for first cousin puts the 401 at the rather low end, plus the Uncle would have been too old to have been my birth Father in my opinion.
If I then look at the matches Maternal Grandfathers Siblings. One is a half Sister, same Mother but different Father, no DNA matches to me there. There is a half Brother, same Father, different Mother. There are two Sons of that half Brother. One is married at the time of my Birth and too old. The other Son is 9 months older than my birth Mother. IF he is my Birth Father then the relationship to my DNA match would be Half 2nd Cousin. A half 2nd Cousin has a match of 10-325 with an average of 120. My 401 match seems high. BUT could the match be higher because there is some DNA inherited from the Maternal side as well as the Paternal side which would bump up the numbers above the standard for a single side match as its a Both sides match potentially??
My problem is I am struggling to find other males of around the right age who could be related to both of us to make a decent DNA match of 401cM.
Any thoughts/comments/criticisms/suggestions welcome, apologies for the post length, I have tried to keep it simple.... Thanks!
