Hopefully this may help, information is based on material the late Fred Fontaine had posted on the old Fontaine web site.
Fred had shown that Frances Goza had married a ___Wallis.
Frances Goza was a daughter of Mary Frances Fontaine born about 1779 and had married John Goza.Besides a daughter named Frances they had a son named Francis Fontaine Goza.
Mary Francis Fontaine may have been born in South Carolina.Her father was Francis Fontaine III and mother was Jemina JohnsonThe father was born in New Bern, NC about 1746 and he may have have been in South Carolina by 1775.Frank was a soldier and said to have been killed in 1781, either SC or Georgia.
Francis Fontaine III was the son of Francis Fontain, Jr. who was born in Virginia and had moved to New Bern, NC by the mid 1700's.
After the American Revolution some of the Fontaines had settled in what is now Colleton County, SC.Around 1800 most had apparently moved to Georgia.Probably to the area of Petersburg, Georgia which is now under a man made lake north of Augusta, Georgia.
