Hi Barbara,
This sometimes occurred because of inheritance, someone would leave a bequest in a will on the condition that the recipient changed their name, this could result in descendants using both names.
The HATCHER CROWTER alias goes back at least to the 1600s. On Ancestry there is a 1662 will in which Elizabeth CROWTER HATCHER is described as the relict (widow) of Thomas CROWTER Todber .
