According to Massachusetts marriage records, Ann S. Thompson was born around 1850 in Somerville, MA to James W. Thompson and a Neola or Nesta (difficult handwriting) Sprague.
She married John W. Rich on the 12th of May, 1867 in Charlestown, MA, at the age of 17. The first child, Nettie, was born seven and a half months later. I have been unable to find any information about further children.
I have yet to find information about her death.
