Margret, I read the messages exchanged: did you receive the proffered data and photos from Jack McCallum -- hope so.
Just yesterday, I began research of a branch of this GERVAIS family (have spent _many_ hours in past years looking for what was swore to me to be J-A-R-V-I-S!) . FWI, FamilySearch.com (LDS) lists your Emma CUBLEY, as TUBLEY.
I have most of my ancestors back to arrival in America, so leafing out the branches of my family tree has become my focus.
