Margaret was born on 18 Jan 1850. She is the daughter of Robert A Martin (1812-1857) & Sarah Scott Bozzle-Martin (1818- ).
She passed away in 1898.
If anyone has more information on Margaret A Martin-Millsap I sure need it. I have seen others post a Mary Beard (1843-1914) as spouse to John Millsap and mother to some (but not all) the children.
