My information on Matilda Duncan is very limited. I do not know her parents. I only know she married William Elkanah Boyd and their three children were 1. Effie J. Boyd born about 1880 and married Floyd J. Hedge, 2. Georgt T. Boyd born about 1884 and 3. John W. Boyd born about 1886. William Elkanah Boyd was the son of Newberry Thomas Boyd and Martha Jane Lefew. Sorry I can't be more helpful.
