Looking for roots in Ireland. My Sanderson line came to America before 1820 and settled in Jersey City. They stayed there until the 1950's.

Do not have any sibblings from here on yet.

Update: Found 3 Sanderson's came to the United States on August 10,1804. Robert,age 69 widower, William age 46 with wife and children, Arthur age 43 with wife and children. They were listed in "British Aliens in the United States During the War of 1812" Compiled by Kenneth Scott 1979,
I am still looking for the name of the place in Ireland where they came from.
