Hello again, Cousin Greg!
Thanks for the info in re: Carl and Rosalia's probable year of arrival to the New World. I was told it was around 1890. 1888 sounds a bit more precise. I'll tell my Dad, Bill Onasch, and his sisters, Dorothy Coyne (still living in New Castle, PA) and Donna Onasch (residing in Andover, MA) the news. You also provided the full list of G-grandpa Carl's siblings. I don't know much about Carl Jr., other than what I wrote in my first message. His wife, Doris, may still be alive (about 97 years old) and residing in FL.
That's about it for now. Talk to you (and any other cousins who may want to respond) again soon...
P.S. If you want to write to me directly, my e-mail addy is email@example.com
