@moonglow123 please forgive me if you thought I was discounting your theory! That was not my intention at all!
As someone who was "just a tourist" before moving here 30 years ago, I've discovered many things about Vermont. I always knew this was "vacationland" for people who lived elsewhere, especially residents of New England and New York, back to the 1800s. It was only after marrying someone who's mom is from here that I realized some folks in the 1920s and '30s married locals while others remained separate as simply vacationers at grand hotels or vacation homeowners. I found it fascinating that my MIL traveled between Boston and the Burlington region regularly as a child and later as a teen, even though it wasn't an easy trip. Roads here were dirt, even in Burlington, Shelburne, and Middlebury. For her, it was an exciting train trip from Boston to Burlington and then a long drive to Grandma's house (sometimes by carriage, sometimes by car).
An interesting note: her Boston family was friendly with bootleggers and her Vermont family owned a general store. Interesting times.
I wish she was still alive so I could ask her if she ever heard about this woman and her children. I truly wonder if her family may have crossed paths with them.
