I have not run across a Jordan Porter. But I was told that my Porter family came from Orange/Culpeper county. We are very light skinned, and when looking at the census of 1880, my great grandfather and great great grand father/mother are all listed as mullato.
Some of my great uncles (porter side) were brown or very light. My aunt was very very light with grey eyes and blondish hair. We have alot of the "white" features. Maybe we are related some how.
