I found a Maria Karl married John... Lennert/Lennest/Lennett.(Dates unknown for both)... Their son, George married Amelia Ploof on January 28,1898 in Brandon, Vermont.Amelia was the daughter of Abraham and Sarah Ploof. My main interest is finding out who Sarah Ploof's biological parents were. She was an adopted child born Sarah Ann Ruston in Charlotte, Vermont 1839/1840.
