Hi I think you're the first person I've come across who's researching Wigmores in Ireland. Unfortunately, none of the Wigmore family members you mentioned look familiar to me.
My closest Wigmore ancestor is my great-great-great-great grandmother, Sarah Wigmore. She married Thomas Henry Sherlock on July 07, 1787, in County Cork. It's my understanding that her parents were Jonathan Wigmore and Sarah (Wakeley) Wigmore. I think Jonathan and Sarah Wigmore's other children were Elizabeth, Jane, and Ann. There's probably a connection between our two families, but not sure what it is. Any thoughts?
