Unfortunately, I don't have enough information yet to tell if this is the same Robert D. Boyd. I don't know my Robert's wife's or children's names.
Here's what I do know:
Robert Boyd and Martha Unknown had the following kids:
James F. Boyd born July 1866 York Co., PA
Isaac N. Boyd born Abt. 1868
John C. Boyd born Abt. 1870
Annie C. Boyd born Abt. 1873
Maggie L. Boyd born Abt. 1875
Robert D. Boyd born Abt. 1876
1880 census, Lower Chanceford, York Co., PA.
According to your obituary, Robert has a sister Annie which matches my information. But, I don't have a brother Jess. W. Boyd. Since, I don't know who the other sister's married I don't know if one became Mrs. Frank Barrett.
