The proof is in the DNA

Much of what I have been working on, in regards to the DNA research within my family, has been kept off of Facebook. I'm sure I've driven quite a few nuts.

If we are related (biologically not via marriage) this may or may not apply to you. I haven't made any decisions on who I will be asking, if they are willing, and when I can afford to test others (unless they want to test themselves and share results - I'm not made of money!).

As a female I am only able to have an autosomal test. Although I can access my genetic information it still begs the question - exactly what did I get from each parent? Conventionally we think we get 50/50 from each parent - wrong. What segments are my mother's versus my father's? I need to explore this more in order to make the testing meaningful. I also need my male Y line (that as a female I can't be tested for).

For starters I can test both of my parents; however, the problem then multiplies. How do I know what segments my mother got from her mother versus her father? The same applies to each side/generation of the family.

My Grandpa Polachek (Frank) is the only member of my family that has an outlying ethnic group. I know for certain my Eastern European results come from his side of the family and his side only. I have zero Eastern European roots except for him. He was a first generation Ukrainian American making him an Eastern Slav. Russians, Belorussians, and Ukrainians are Eastern Slavs that are closely related. If you look at the chromosome map below this shows individuals I match with on certain segments, notice we all overlap each other? We are all likely to be distantly related to each other. Every result is someone that is exclusively or primarily Eastern European - or I share no other common regions with them. Although speculation, I can only guess these overlaps on chromosome 2 are from my Grandpa Frank's family. If they are relatives of his father Lukas or his mother Yulia - that remains to be seen. 

Since my remaining three grandparents all have either Scottish, Welsh, or Irish ancestry - that overlap, that alone cannot help me rule some results out. 

My goal for testing will likely be something like I'm about to list below. I've not asked individuals if they would consent to a test, so please do not be alarmed as this is just an idea I'm working on.
If any of you are interested in testing please let me know. Again, it'll take me a bit to get the money to pay for all of this so if you'd like to test on your own & pay for it instead of waiting on me - message me so we can chat about it. I will take responsibility of administering & protecting (privacy) your results. It's a painless saliva test. This is not inclusive & I welcome anyone wanting to be tested. Testing is $50-$200 depending on what website & platform you test.

My mother's side:

First test: Test my mother or one of her siblings.

Second test: Test one of my mother's first cousins, preferably a male Polachek that is a descendant of a male Polachek. In this case that would be one of Uncle Steve's or Uncle Mike's sons as they carry the Y-Polachek line. That will then isolate what DNA came from my Grandma Marge as the cousins will not share her DNA. Note: I could use my mother's brother for the Y line but that won't help me filter my Grandma Marge's genes.

My father's side:

First test: My father or his brothers.

Second test: My paternal Aunt Linda or my paternal first cousin Cher. They both carry my Grandma Dorothy's mtDNA. Depending on the type of testing my father & his brothers complete I may or may not need a mtDNA test from my aunt/cousin. 

Third test: One of my father's first (maternal) cousins. They are male children of my grandmother's brother. This will give me access to determine what markers belong to the Leisenheimer's (Grandma Dorothy's family) - including the Y line that none of my uncles & aunt can test for.

Fourth test: Have one of my distant (3rd or 4th) Holan cousins test.  (My Great-Grandma Miles was a Holan.) Although limited, it will narrow down the Czech line leaving any other results to belong to my Grandpa via default.
