We can assume that Agnes’s father’s last name was Glover. Because when she was born, her mother’s last name was Wells. There is no other reason to give the baby a different last name than that of her mother.
When Agnes Glover was only two, her mother married Charles Parr. From that time forward Agnes normally used the name Parr as her name. When legal names were required, such as on the marriage certificate, this caused some confusion, and sometimes led administrative personnel to “correct” documents.
