Louisa's middle name of Matilda is from a descendent of her son Perry.
Matilda is listed as Louisa's middle name on the marriage certificate of
her son Perry Hall Black. It is also recorded in a notebook started by
Louisa's granddaughter, Perry's daughter, Blanche Olive (Black) Grewell.
However, it might have been a mistake on the marriage certificate: a
case of the clerk confusing the bride's name with Perry's mother's first name.
