Rachel,
I think I know your father. Does he live in the Tell City, IN area? I have not attended an Esarey family reunion for many years. However, this year I do plan to attend.
The family orginated, to the best of my knowledge, in Devonshire, England. I did some research on the name and it correlated with the information in Logan Esarey's research.
I hope this helps.
Liz
