Sandra, thank you for your illusive hunt. I had read the first posting and thought, "How did she ever go there... with Thomas?" Then I saw the next one, and was relieved.
I really think that it was a scriviner's error and that Izzy was the Ames because Amos is so little known in Northern Ireland. I think in all of my searches around there we only came up with a handful and none of them proved out. I will now go back over it and try again. That there were three girls, or sisters, that all indicate that they were from Ireland is an indication that there is something there. And, the fact that Patrick took Mary to Scotland so he could find work and is shown in two census records but there is no record of his death complicates the whole darned thing.
Also, when I said that John was a bit imaginative that was an understatement. He held out that he was a highlander and good Queen Victoria had given him the Highland Outfit that he wore to America - and he never was near the highlands being more familiar with Paisley and the Glasgow area. He denied he was Irish and held out he was a Scot, born in Scotland, and this was in an Irish comunity (in the late 1800s San Francisco was over 30 percent Irish!). But, we don't have a record of his father's death.
That is why I had turned to attempting to find something on those two sisters.
Oh well, for an old man it is much more than a game. Actually, it is now easier to keyboard than it is to talk due to a stroke that does keep me from blathering too much. But, I guess I make it up with all of this posting.
Again, thank you very much. Jim

Whhhooops, something more just came in.
No, I don't have information on his marriage previously. Could it have been his son?
But I will look it over and let you know, after I shave and shower. It is 8:15 in the morning now, in the High Desert of Utah. Jim
