I note that a Richard Welwood (51), Clerk in Holy Orders, Church of Ireland, born Co. Wicklow, wife Susan (48) born Co. Roscommon, and Susan Rosboro (17) servant, born Co. Longford, were residing in a household in the Townland of Glebe, Civil Parish of Fenagh, Co. Leitrim, Ireland, on the 1901 Census.
Hopefully, this snippet will provide "just the right clue" to a Welwood researcher.
