I think that perhaps the parents of Robert Patterson Boyd are Martha Patterson who married a man name Boyd and who was killed in the Revolutionary War and then married James Norton. I am related through the Norton line but have a letter to Thomas Patterson Norton from his sister, Esther Patterson Harper in 1842. She lived in Illinois and he lived in Ralls County, Missouri but she mentions that Patterson Boyd had died. The parents of Thomas Patterson Norton were Martha Patterson and James Norton. The Robinson family is very interesting. Contact me if you want more information.
