To add a postscript to my previous note, my research focus has been on the paternal sides of my father's side. In other words, I have nominally researched from 1800 forward the maternal sides forward these fellows married into. I am nearly run out of research on that side using ca. 1800 as the starting point and in many cases have people my own childrens' age found.
I guess the families my various grandfathers married into is in store for research over the next 11 years! ;) There will be more stories, family photos and finding I have surprise double or triple cousins out there!
