Sandra! Thanks so much!
Hugely appreciated!
I have a feeling in my bones this is the right one. In fairness, looking back at mention of Nicholas on each headstone, they said he was 70, when he was actually born in Dec 1867 and died in Feb 1946 so was 78!!! Same with a lot of people in those days with discrepancies over ages... Doesn't make researching them very easy!!!
Going to go looking around the Newton area of Boston now for more clues.
Thanks again!
Caroline
