I am looking for information on my great-great-great grandmother, Miss Suffern (I don't know her first name. She married William John Garvin (about 1770-1830) from Castledawson in Derry County, No. Ireland.
They had a number of children, including Steven Garvin, my gr-gr-grandfather, who married Isabella Suffern (about 1797-1852).
They had 10 children, one of whom was James Suffern Garvin (my gr grandfather, who married Martha Millar. My grandmother, Annie Elizabeth Garvin, was the youngest of their 14 children. She married Samuel Mawhinney of Bellaghy, No. Ireland, and they emigrated to the U.S. around the turn of the century, or a bit earlier.

Any information anyone has on either of the Suffern women would be greatly appreciated.
