Greg, how are you?Before my father, Richard Innis (Aunt Melva's brother) passed away we did some research on our heritage.Marvin Abraham Innis' parents were Henry Charles Innis (1859 - 1904)and Rose (Frank)Innis (1859 -1942.Henry's parents were Col. Adam R. Innis (1835 - ?) and Mary (Flecher) Innis.Col. Adam's father was Rev. Henry Innis (1792 - 1865) and his mother was Isabella C (Pegg) Innis.His father was William Innis from Phidelphia.William is in the 1790 census for Phildelphia County on page 198. I have not been able to get anything before this time other than the posibility of being related to William Innis who arrived with 7 children and his wife Percy in 1674 in Maryland.This was derived from the book early Settlers of Marlyland by Skordas.Hope this helps.
