I have two Caleb Lakes in my tree. I have a Caleb Lake that was born in 1780. He was married to Francais Mosher. They had a child, and they named him Caleb Lake Jr.(b)1807. He married Margaret Skalling. I don't know if they carried on the family tradition of passing on the Caleb Lake name, but the only child that I have for them is William Dyer Lake. You might want to check out this link. There are some Caleb Lakes listed here.
