My grandfather, and great-grandfather for that matter, lived in St Marys, WV. Pretty much all their lives. They come from a long line of Williams and such. As a sidebar, my great-grandfather had a photography studio on a riverboat - but eventually parked it in St Marys on the Ohio.
My father lived in St. Marys all his life until he went to WVU and then off to WWII.
Since these marbles came from my grandparent's home in St Marys, I am pretty sure most were collected prior to my father's adulthood (born in 1917, off to college in the 1930s).
