The names of Watts, Smalley & Fountain are mentioned in the Vital Records of St. George, ME. All were very large families in the area. I don't find any Gogarty name mentioned. The Watts family was from both Thomaston, ME and also St. George. My best friend is a Watts and I have done research for her.
The Smalley family was also a very large family in St. George and I am related to that family.
The Giles family was also a large family and I am related to them and also have some friends in the area that go back to the family. I would need a little more information in order to give more specific information as their were many George's and Williams Watts. Most families from St. George did go to the Boston area in the early 1900's. I have a Seymour U Watts, b. 4 Apr 1855 married to Eliza E. (Wilson) who is living in St. George in 1895. This Seymour was a Sea Captain and the Cemetery Records show that him and his wife were lost at sea Jan 1901.
With a little more information I can probably give you some names and dates.
