Hi, thanks for your comments.
Edward Wallace arrived in New York City. He travelled alone as he was not married at the time. His ship sailed from Liverpool. I am not sure, but the best match in emigration records shows an Edward Wallace, approximately 27 years old, arriving in New York aboard the ship Fidelia in 1847. His occupation was listed as Mason. I suppose he emigrated due to the famine conditions at that time in Ireland.
Edward would not be in the Tithe Appointment books since he was not a head of household at that time. There is an Edward Wallace in Griffith's Evaluation living in Columbkille in 1845, but I really don't know if that is him. I had to choose a parish (I would have preferred to list just the county) in order to post, so that's why I listed Columbkille.
I've checked LDS but they have nothing. I've also written to Rothe House and provided them all the info I have, but they responded that after some checking of church records (Edward was a Catholic) they couldn't find a match for my Edward, and that Wallace is not unique enough a name in Kilkenny to dig deeper without more information.
Edward has become my genealogical "brick wall", but I'm not surprised since, after all, he might have been a mason. :-)
Best,
