Hi,
I too am interested in Ellison Ismay (male) b 1849 Newcastle upon Tyne, Northumberland, England. He went to live in USA about 1888, and lived in Pittsburgh PA and Carnegie, Allegheny PA. In 1899 he married Cora b.1877, I believe her surname may have been Allen, she died in 1956. I know they were on US Census in 1900, 1910 and 1920 but beyond that I know nothing of their US history.
I have knowledge of his family history prior to sailing to US. Just drop me a message if this would be of help to you.
Tony.
