Hi Phil:
I was looking for the family as merchants. I do remember seeing engravers. I saw the following last night, but didn't read all of the names, since his occupation was engraver.
1850 Williamsburg, Kings County, NY
James P Major, age 32, born in England, Engraver.
Mary, age 10, Frances age 5.
Richard, age 24, born England, Engraver.
Maria, age 22, born England.
Sarah age 1.
All children born New York.
Also included with this group was Henry? Thrush, age 22, Printer, born England.
I have managed to find that Henry THRUSH was a cousin of James MAJOR. His mother - Ann - was a sister to James's father - Richard - so this census entry ties the two families together very neatly.
Thanks for helping me to solve this challenge.
Kind regards
Phil
