We are talking about the same line. The Robert
Vose publication and Ellen
Vose publication is available, I believe both via ancestry.com in their publications section, which I attached certain pages to my tree. Edward
Vose, who married Florence
Rockwell, was the son of George E. Vose, who was the son of Elisha
Vose, who was the son of Josiah
Vose, etc. This line goes up to Robert
Vose. Your mother-in-law was the daughter of Robert "Roy"
Hobson Vose?" If so, then we are related via marriage.
