I had all your mother's siblings except for Marie.
As for the children of William and Elizabeth I have: Mary Catherine who married Kyran Bryan; Honorah "Nora" Butt who married Edward Bryan (brother of Kyran); Thomas Butt (Dave's mother always had Uncle Tom Butt visit her in Fogo. He moved to Boston when he was young and died there. That's why I've got Thomas).; Michael A. Butt who married Josephine Alyward; Walter Butt who married Alice (this is another case of Dave and his siblings knowing of their mother's Uncle Walter who visiting them in Fogo); Peter Butt born June 19, 1891 Cape Cope baptized July 27, 1891 son of William and Elizabeth - Per Vital Records Fogo Book 2; Margaret Joseph born Nov 26, 1892 Island Harbour baptized May 26, 1892 daughter of William and Elizabeth per Vital Records Fogo Book 2; William Butt married Margaret Maude Miller; Anne Josephine Butt married Thomas Lynch.
I have some birth, death and marriage dates for these.
We live in Baie Verte, NL. Where do you live? We were up to Fogo a couple weeks ago and made a visit up to Island Harbour to see Dave's Aunt Loretta Bryan. Ferg had a store in Lord's Cove where Dave and his family lived.
