I have an Elizabeth Kingston born in 1800 in Bandon, County Cork. Don't know if this is the same one that you're looking for and I don't know who she married. She was a daughter of George Kingston and Hester Holland, both also from Bandon. Elizabeth's siblings that I know of were William Holland Kingston, born 1799; George Strickland Kingston, 1807; Lydia Ann Kingston, abt 1810; and Mary Catherine Kingston, 1813.
I don't have a Jane Kingston in my files or any Dealy family members.
