Randy at Genea-musings has posted his Saturday Night Genealogy Fun idea:
The challenge is this:
Provide a list of your paternal grandmother's patrilineal line. Answer these questions:
* What was your father's mother's maiden name?
* What was your father's mother's father's name?
* What is your father's mother's father's patrilineal line? That is, his father's father's father's ... back to the most distant male ancestor in that line?
* Can you identify male sibling(s) of your father's mother, and any living male descendants from those male sibling(s)? If so, you have a candidate to do a Y-DNA test on that patrilineal line. If not, you may have to find male siblings, and their descendants, of the next generation back, or even further.
My father's mother was Edith Louise Olson, b. 1911 in Titusville, Crawford County, Pennsylvania; d. 1981 in Redding, Shasta County, California. She had only one brother who had no children.
Her father was Frederick Olson, b. 1882 in Dahoga, Elk County, Pennsylvania; d. 1966 in Sunnyvale, Santa Clara County, California. He did have one brother who had sons.
Fred's parents were my most recent immigrant ancestors. Most of my ancestors were here from colonial times. Johann Erik Olsson; born 1839 in Nysunds Parish Varmland, Sweden, arrived in the US with his wife Louisa in 1871. I do not know if any of his siblings came with him (for males as a source for y-dna testing). Swedish parish records are wonderful, but a lot of the names are very much alike because of using the patronymic naming system. Of course they didn't continue the practice here at that late of date, but most of the names are just variations on what seem to be a limited number of first names. Because of that, the fact that there was a man of the same last name who submitted his declaration of intent at the same time as John may not mean anything. In the Swedish parish records Johan does have a brother named Anders which, if I recall correctly, is the name of his fellow applicant for the declaration of intent (and oath of allegiance, too, I think--both made me think there was a strong connection). This little exercise forced me to check that fact that I hadn't before.
John Erik Olson's father was Olaf Persson, b. 1794 in Karlskoga, Orebro lan, Sweden. (I have not learned how to do all the proper symbols for Swedish spellings.)
Olaf Persson's father was Peter Jansson, born in 1751 (no location in the last parish record I consulted for this line).
Both of these last two did have other male children. It would be interesting to track those lines forward to see if I have a resident Swedish cousin. Parish records are so great for Sweden (see Genline), that it seems to make y-DNA testing less important.
The other thing I thought interesting about this exercise is that my ancestor in each family was born to a father that was older than average. Fred was 29 (not so old, but my grandmother was the oldest child); John was 43 when Fred was born; Olaf was 45 when John was born; and Peter was 43 when Olaf was born.
