Sarah Jane Marler is my 4th great grandmother. Her daughter Mary is my 3rd great grandmother. The photo was not fully labeled. I imagine the unidentified woman may be Sarah’s other daughter from her first marriage, Philomelia Lake. She had many other children with her second husband so I suppose it could also be one of her daughters from that marriage. I really wish I knew for sure. It makes me want to go label photos right now! Despite the missing details, it’s a lovely photo. I’m glad to have it.
