Andrew Marshall Good and his brother John Washington Good were living with my Hunt ancestors. Phillip Hunt, who supposedly never married, ended up leaving everything to John Washington Good, and it's in his will that John and Andrew's father is named:
"Pike County, Kentucky - Last Will & Testament of Phillip HUNT, 1842, Book A, Pg. 21 - Heir John Washington Good, infant of Wooby Good. George Hunt. Wit: Nathaniel Roberson."
I have never been able to locate anything on this Woodby Good, but I highly suspect that Andrew and John's mother must have been a Hunt, thus the boys living with the Hunt's.
