ANTIQUE SITZ ARTIST BRIDE PORTRAIT 1842 Southern Child Added Later OIL PAINTING

See photos. About 14.5 x 11 1/4. I am the 3rd owner of this painting, the sitter being the first owner. The second owner purchased from a former reputable estate sales co in KCMO. I shopped them. I purchased from another reputable estate sales co. You can see the paperwork. Painted on a wood panel? The bride, once she was a mother, added her child who must have favored her father. I think we see a daughter. I am assuming this is from the south per the notes. I don’t know if the sitter is identified on back. Sitz is the painter. Sold as is. Remarkable condition for the age. Crazing throughout and roughness on the edge. Beautiful, imo.
