I find only one Luanna in my database--and she appears to fit the time frame and location.I don't have a record of Luanna having married anyone--but records for that period are spotty at best & the lack of a marriage document means nothing.
Luanna was born 16 Apr 1768 in Farmington, Hartford county, Connecticut to Oliver and Lucy (Stow) Hungerford.The only other child I show listed to this couple is Harvey Hungerford who was born in Farmington, CT on 12 Dec 1773.
Oliver was born 1744/45 in East Haddam, Middlesex county, CT, was christened on 10 Mar 1745, and married on 24 Dec 1767 in Farmington.He was the son of Capt. John and Deborah (Hungerford) Hungerford.
Oliver can be found in the 1790 census in Harpersfield, Montgomery county, New York.This gets the family into New York!Do any of these names help you make a connection?I would like to help you in your research.If you have any other tidbits that could shed some light on this don't hesitate to contact me.I will alert you to anything I come across in my research.Take care.
