I can't find much on the Internet about Milford other than a few pictures.
One set of pictures did say that Milford was also called Grice House.
In the Arcola-Roseland Cemetery in Arcola, Tangipahoa, Louisiana is the grave of a man named Warren Ashley Grice.
His tombstone clearly says that he was born at Milford, Camden County, NC on 30 Nov 1816.http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=62...
Is(was) there a town named Milford or is the tombstone referring to the plantation?
