There are a couple of small points to note here.
Harrison, the oldest child, is said to have been born in West Waterford, Maine. It is said that his father, George Ball, was born in Maine; married Nelly Fay (their intentions were published September 8, 1816), had their first child June 1817 in Maine, and then returned to Westborough. This means that George had to return to Southborough / Westborough long enough to meet and court Nelly (not a short process), marry her in her hometown, then return to Maine for long enough to have one child, then return to Massachusetts. My feeling is that he returned to Massachusetts to settle, then married and had Harrison in Westborough just like all the other children. In the three years of census where I have found Harrison, 1850, 1860 and 1870, he is said to have been born in Massachusetts. His death certificate clearly states that he was born in Westborough.
Harriet married Levi Smith, not Lewis Smith.
- Clarissa is referred to in all but the very first records as "Clara," as are other Clarissa's in the lines. It's almost as if for this group Clarissa is a child's name, Clara the adult form.
- I was not able to learn what Samuel's middle initial R. stood for. In every one of the records I found, he is referred to as "Samuel R." except for one where he is mistakenly called "Samuel N."
- Because so many of the first names were missing (e.g., "Clare" -- who turned out to be Clara” married an Emerson, Nellie married an Archibald), the source that proved the most helpful in this research was the list of vital records for Massachusetts 1841 - 1910, published by NEHGS.
- Charles A. Brigham is supposed to have gone to California, and there is a Charles A. there in 1870. However, it says that he was born in New Hampshire, which does not seem likely, especially in view of the “Westborough” in both Orlin and Brigham. It could just be a mistake.
