My grandmother was also a Voegtly. She was Virginia Voegtly, born in Pittsburgh in 1900. Your grandmother may have been my grandmother's first cousin. I do not know anything about Elizabeth Voegtly, but my grandmother's siblings were William Voegtly, Gertrude Voegtly, and Chester Voegtly. They were all born in Pittsburgh, children of William Voegtly senior and Mary Quinn.
Please let me know if you have further information of our relations and what we are to each other. I live in New Zealand, having been born in Youngstown, Ohio in 1951.
