Thanks, Jane, Roger and Tim,
The guess was that William Foley the elder b. 1779 in Listowel, County Kerry, married Catherine Cotton b. ? possibly from England. Cousins believe the Cottons hailed from England because my DNA test surprised us showing DNA from the midlands of England. We--to this point--can only find one birth reference and that is to a William the younger b. 1812 in n Castellyons but perhaps baptized in Limerick. Now that I write this down I see that looks odd. Thanks for the links.
My Foley family was quite secretive about its history. Once they hit Canada, we can see they are adventurers, trying farming and then building small general stores in Canada and then in Wisconsin. They made money selling land in the 1890s but otherwise were poor, at least in money, but perhaps not in spirit.
They ended up in Milwaukee, Wis, about 90 miles north of Chicago on Lake Michigan, in an enclave with all my other great-grandfathers and mothers in the boom of the 1890s. They and my other great-grandparents, mostly from the Robinson Expedition, were very poor when they came to Wisconsin about 1840. They pioneered the state. Somehow in one generation, they went from poor farmers and miners to doctors and lawyers, my grandfather's generation, who pulled us out of poverty. They were all intense workaholics and very different than the friendly, laid back people we have met when we have visited Ireland.
I am in the last phases of writing a memoir on how the spirits of our rugged individualist but clannish Irish ancestors inspired us with their values. I pray to them the way one would pray to a saint. In my mind, they were true, boots on the ground saints whose miracle was me.
Best, Ellen
