There might be a bit of confusion here (I'm certainly confused with the addresses). There's a Kingstown, Rhode Island and a Kingston, Rhode Island (University of R.I. campus is there).
Kingston, R.I. is north of South Kingstown, R.I. which is in turn just south of Warwick, Cranston then Providence.
From what I can see on Google maps, Old Forge Road is in North Kingstown.
Ancestry tree was giving North Kingstown.
