There were two Culbertson's Rows - one in Ireland and one in Franklin County. The settlement once called "Culbertson's Row" in Franklin County, is now just plain Culbertson in Greene Twp. My husband and I talked about this last evening - it is now the name of small settlement just east of the Letterkenney Depot main gate at the along Route 997 where it intersects with Route 433. There is a tiny railroad depot on 433 just south of 997 called Culbertson's Station.
Note: I do not have a Culbertson line, but had collected information on them due to their intermarriage with the Porters.
