    Hard to work this one out

    C, M and W are a matrix match with my father. M and W= chr 1 and C=chr 12. M has an ancestor with our family surname.

    C is a match to me , but M and W aren't .

    Your father has 2 chr 12s and 2 chr 1. Seems like you got the section of chr 12 that matches with C, but not the section of chr 1 that matches with M and W.

    Does your dad have common matches with M or W that are on his patrilineal line? Or at least that seem to be connected through his father's family or paternal grandfather's family?

    Have you tried chromosome mapping? I'm currently finding it very helpful.

    Some good questions. My father did a Family finder test as a favour for me , but has not made much of an effort to pursue things further. He's 89 , and quite old school when it comes to genealogy.

    Matches with people with our family surname or ancestors with our family surname are few and far between. I have a 37-2 Ydna match with another Gatty who refuses to do more testing despite my offer to pay. I am a 27-10 4th cousin-remote cousin match to someone with Gatty ancestors . My father is a 39-9 5th -remote cousin match to that person. That person doesn't form a matrix with C,M and W.

    Our Gatty line is stuck at my 4th gt who was married at Liverpool in 1810 . M has a female Gatty ancestor who was born at Veryan ,Cornwall in 1704 . Bridging the 100+ years gap has proved fruitless. The Gattys were first found in England in Cornwall. There is talk that they were originally Gatti's from Insubria in Italy .

    Chromosome mapping sounds interesting , but a little too complicated for me to do. Perhaps if there was an 'Idiot's 101' about it .

    DNA painter is a super easy way to do chromosome mapping.

    I tried that, and didn't get on with it .Ideally I'd like to group together all people my father and I match with a Gatty ancestor , and any shared matches we have. Last time I tried with my mother's ancestors I ended up with several ,separate profiles.


    I'll confess that organising and planning is a major executive functioning deficit for me.

    I found it really helpful to group my matches (the largest percentage of good ones being on Ancestry) by grandparent they connected through and, later, as I had more known closer matches, to identify them with great-grandparents. Now if I get a new match I can usually tell where they probably connect using shared matches, which helps me to eventually figure out the actual connection. I've also done a lot of tracing relatives I do not descend from directly forward, to find out more recent surnames.

    Do you have any other identified somewhat close relatives on your father's father's side on FTDNA (or, if not, on your father's mother's side)? You can use that to at least see if the Gatty-connected people are matching on the right side (or not matching on the wrong side).

    It's definitely harder to place matches on FTDNA on average than at Ancestry (although Ancestry is useless for chromosome painting). Have you checked for good matches at Gedmatch too?

    (I know that Americans are more likely to have close matches on the testing services just because more Americans test, so understand this process could be a lot tougher for you, as you may not have so many.)

    My father's data is only on FTDNA,Gedmatch,and My heritage. I've tried using search on Gedmatch to find people with Gatty ancestors and then to do 'people who match both or 1 of 2 kits. It's a waste of time as there is no longer a box you can tick to compare matches for shared autosomal dna etc.
    I'm clueless as to matches on my father's father's side other than those already stated.

    M is a match to my father on My heritage but they share 163 matches ! To tell you the truth I'm completely stumped and disillusioned . I even added my YDNA to Yfull with little to show for it.
