About Amanda Arnold
Amanda and George sort of "eloped". The lore is that he rode into their yard and took Amanda away to be married.
They had a hard life. It was especially hard for Amanda. She had two pregancies of multiples that either miscarried or were stillborn. When Sidney and Amanda, twins, were born she died soon afterwards. The twins lived about 3 months and also died within a day of each other, whether because they were premature or malnourished I don't know.
