FamilySearch has her listed as "Releaf Procter" b. Apr 24, 1810 Swanville, Waldo, Maine, USA
They also have a few of her and Joel's children birth info; however, they do not list her maiden name.
1860 Census has a Joel and Daniel (Separate Listings) in Rockland, Knox, ME. Don't know if that is her spouse and son or not. May indicate she died before 1960 since she appears in 1850 census.
