Cynthia was my 2nd great-grandmother. She was the daughter of Thomas P. and Laura (Backus) Richmond. Cynthia married James More, a native of Scotland, whom she met while still residing in (Livingston County) New York.
According to an 1884 History of Lapeer County, Michigan, [James More] "...was married in 1851 to Miss Cynthia Richmond, of New York, by whom he had six children." James, my 2nd great-grandfather, died December 26, 1870, in Lapeer County, Michigan.
When Cynthia died in Lapeer County on March 2, 1912, her name was given as Cynthia Moore (More and Moore are used interchangeably). She's buried next to her husband, James More, in the Thornville Cemetery in Lapeer County. She listed as a More in every available Federal census from 1860 to 1910. Case closed, right? She never remarried, if she died as a More, right? WRONG.
For the longest time, I never knew that Cynthia had remarried. Oh, there were clues. A plat map listed a Cynthia Marshall in the neighborhood where I expected to find the Mores. However, after spending many, many hours in the Lapeer County Register of Deeds (primarily looking for clues about Cynthia's parents), I found the "smoking gun." The evidence was found on Lapeer Co., MI, Deed #49-594.
Now it was time to look for a marriage record (this was done a few years ago, the old-fashioned way at the Library of Michigan -- it's online now).
Cynthia and Sylvester Marshall were both grantors on Deed #51-468:
Corroboration: On the 1894 MI Census, Lapeer County, Cynthia More was living with her son, James, d-i-l, Rosa, and granddaughter, Maudie. Cynthia More was 64 years old and "divorced."
Here's more information about ex step-great-grandfather Sylvester Marshall; Sylvester as an heir of Josiah Marshall and something about Marshall's mother's heritage.
