Steve,
After reading your message a couple of times, I noticed
that something didn't seem right. You state that:
The stones were eroded and difficult to read so I have no
exact date, but it is definitely the right Martha since the
stone says, "Martha A wife of W. Calvert" and is buried
next to William and "William M. son of W & M.A. Calvert"
(born 1846, unknown to O'Gorman but clearly listed in the
censuses with William and Martha).
Martha A. (Mitchell) Calvert died Oct. 1864 about 16 years
before her husband William who died June 2, 1880. Their
son William all most certainly died as a child. It is difficult
to envision a situation where a grown man with a wife and
children would be buried next to his mother and father with
a tombstone reading "William M. son of W & M.A.
Calvert".
"William" was a popular name among the descendants of
William Calvert who married Elizabeth Nodding. I certainly
believe you are in the correct branch of the family tree,
however it was probably another William, perhaps a
cousin not listed in O'Gorman. For example, Leonard
Calvert married Roxie Morley. Here is another chance for
a William with the middle initial "M".
The information shown in O'Gorman comes from
descendants of William Calvert and Elizabeth Nodding,
not from Ella Foy O'Gorman's personal research. For this
branch of the family, there were a number of descendants
born in the 1870's and 1880's who were still alive at the
time O'Gorman was researching the Calverts. When you
read the book, you find things like William Henry Calvert
(b. Dec. 25, 1863) was a blacksmith living at 7000 Agnes
Avenue , Kansas City, Mo. There is no death date given,
however the word "was" is used. This tells me we are
looking at research from the long, long ago.
