I have many DNA connections on Ancestry, I come from the Mormon genealogy on my maternal side, one great great uncle had 2 wives and 27 children! (Taylor line) Of all my connections on Ancestry I'm perplexed by a very close DNA relation I'll call 'Jane', whose listed between my half brother and half niece, so she's a very close connection, our cm number is 1142. I'm ready to hire a professional, but looking into it the cost is prohibitive.
Jane and I have been talking for several years now trying to figure it out. She has a complex background. She was not raised by her parents, her birth certificate lists the name of a father who she only met twice, he's long gone now. She doesn't have a lot of known family connections, all those she knows are on her mom's side, but her mom was not a straightforward lady in her stories and gave her away as a toddler to a couple she didn't know, to be raised.
She's about 18 yrs older than me, about 4 yrs younger than my dad, and connected on my father's side somehow. Our 'families' are from the West Coast/Northwest areas.
My dad does not know his biological father, so we have a gap, but with the close DNA connection to me it seems like she is either half sister to my dad, or 1st cousin is a second obvious match. But there are no matching names in her known tree (which is very lopsided and in question of accuracy with it being mostly through her mom, of what she knows) or mine, and of course I don't know my paternal side to know what names to look for.
What is the best way to find our connection?
I've tried doing surname searches in our trees, there's a small group of people we share DNA with, none of them are known to either of us. I've been looking on the Internet for tips on finding the connection.
I feel like this is an impossible situation, yet we're so closely related it seems it should be obvious, or easy. Unfortunately, it seems secrets, adoptions, lies and so forth are the most common thing we share with our ancestors.
