It's a shame that more of you don't have the Ainlay (with an 'a'!) Genealogy, done by Margaret Ainlay some years ago and copied (so far as I know, there is no digital record) and distributed along with an extensive round robin letter circuit with photos. All of that has stopped now. My copy of the revised genealogy is back home in America (I'm teaching in China for several years) so don't have ready access.
The genealogy begins with John Ainlay arriving in Port Hope, Canada, in 1819 with three children, one of which was William Ainlay, founder of Ainlayville (now Brussels, near Toronto).
Most of the early US Ainlay history is in rural Nebraska, but maybe everyone knows this already. My dad (also Gene Richards) married his second wife who was his cousin, Maxine Richards (nee McNickle and mother married into the Ainlays). She has been a wealth of information but is quite old now, living in Washington.
I have only kept with me my direct line - John to William to John to Effie Ainlay, one of at least 13 siblings (not 12) mentioned previously in this thread, who married my gf Herman Richards (nee Grejcer from Russia, now Belarus).
