I have just discovered that my great-great grandmother's name was Matilda Ashley. She was born around 1820, either in NY or NJ, according to various census information. However, her family also seems to have a Maryland connection; her son Ashley Willis consistently indicates she was born in MD. She married William Willis, but it appears he may have died early, because Ashley lives in Maryland with other Willises in the 1850 census. (Perhaps Ashley was confused and his father, not his mother, was from MD!) Matilda appears in New York City in the 1860 census, living with Ashley and 2 other Willises, Henry and Mary, who may also be her children. If anyone can give me a lead on this Matilda Ashley Willis, I would appreciate it!
