There is a Joshua Ogg in the 1800 US Census of Somerset County, PA.Not sure if he is related to William Ogg-who also lived in Somerset County--see below.
I am trying to puzzle out a connection between the Ogg and Tisue families of Southwestern PA.There is a Phebe Ogg Tisue who is the wife of William K. Tisue in the 1850 census of Fayette County PA.Living with this family are Catherine Ogg age 78 and Hannah Ogg age 64.
There is a Catherine Ogg in the correct age range as head of household in the 1840 Census of Somerset County, PA. Turkeyfoot.
In the 1830 census there is a William Ogg in the same area as Catherine Ogg appears in 1840--he is not in the 1840 census. Turkeyfoot.
