Bowdoin was the same artist who married Florence Tapley, daughter of Gilbert Tapley of Danvers. They had two children: Gilbert Tapley Bowdoin and Fidelia Bowdoin, named after their maternal grandparents. Gilbert lived in Lynn and Fidelia in Danvers; neither married. I have 8 ambrotypes of members of the Tapley family, including a full plate of Gilbert Tapley. Only one is marked. It shows his nephew Walter Tapley with a maid and is labeled "AMBROTYPE BY/BOWDOIN" and " JTTING'S PATENT/JULY 4 & 11. 1854"
