I am looking for information on my gr-gr-gr-grandmother, Miss Suffern, who married William John Garvin in Castledawson, County Derry, No. Ireland, around late 1790's. They had 2 sons, Stephen (b.1798) and John (b.1799). Miss Suffern's niece, Isabella Suffern (b. 1799), married Stephen. Isabella and Stephen are my gr-gr-grandparents. Isabella Suffern may be the daughter of a James Suffern (b. 1760) and a Miss Young.
If these people sound familiar to you, I would love to hear from you.
