Her surname is unknown but she was apparently, the person listed as "Great (Greta) Harman, aged 45," in the 1708 census.
This surmise is strengthened by the fact that three of the daughters named a daughter Margaret.
In the census return, the other members of the family are grouped in a manner which would indicate that they were all of one household. (NJMis:I:153).

[cos1776 note: Caution! Age 45 in the 1708 census means she was born Abt 1663, making her 5 years older than Husband 1 (possible) and 23 years older than Husband 2 (unlikely). It would be helpful to post the content of the 1708 census.]
