mayor al –
 
I am indeed male and probably should have said so although I think that that your remarks made that a given if I had anything valid to say.  My remote ancestor, ‘”C” as designated above, lived from ca 1605 – 1687 and IIRC I am ten generations down so our circumstances are similar.
 
I suspect that your genetic test service will if you desire, like mine, send you the names of others with the same markers as you have.  In my case only a few of the names are the same as mine and mostly I have never heard of them.  It is very interesting. 
 
It is interesting also  that you have a Czech heritage.  I DO NOT, SFAIK, but my mother’s family was in the 16th century likely living in the Sudetenland, South Germany, the border territory that was Hitler’s  excuse for grabbing part of and later all of Czechoslovakia in the late thirties.   I am sure that your family there has horrific stories to tell about those times and the Communist era after the War.  My mother’s family moved to Prussia by the 18th Century and later to Russia before coming to the USA in the 19th Century.
