Hello - I am back researching this family, and discovered your message!
I have some information that links Mary Ann Chappell to some of the Horle families found in Skaneateles.
I believe all these families are related, and that they emigrated to the US from Banwell, Somerset England. I am interested in these families as I am a direct descendant of Thomas Horle, born 1821 in Banwell, to James and Sarah (maiden name unknown) Harl/Horl/Hurl.
I have more details if you would like to discuss.
