The probate for Ephraim Puffer in Stow, Massachusetts, makes one reference to the last name of his widow Mary's new husband: Crown. However, when viewing the records of the widow's father's probate settlement it become clear the last name was actually Brown.
I spent too much time looking for Crown because my research was based solely on the probate of her husband. When I decided to quit looking for Crowns and went back to researching the widow and her family of origin, I found the other reference.
Sometimes you have to look for someone else to find who you actually want.
