Hi there John, I'm just finding out that my ggrandmother was Catarina Wynne she married Bernardus Healy of Killaraght, Sligo. They had 3 children Bernard, Catherine & Dennis... can't find any more.
Looking at your post I see a similarity in the family names, we have a Michael, Mary, Winifred, James and Bridget (Bea). My grandfather was Michael son of Dennis. My father was Michael Healy who had a brother Dennis and John, sisters Mary and Winifred. Also 6 boys who died early. my gf immigrated to Boston, Massachusetts.
Went to Ballymote & Killaraght in May to do some searching and that is where I found out about Catarina.
Ironically my new grandaughter's 1st name is Wynne but when she was named we knew of no connection.
Hope this is a match.
