John J. Floyd, Floyd's Township, Horry Co., SC

In the 1910 Floyd's Township, Horry Co., SC, Household #62 is Floyd, John J., age 50, married 28 years with wife Nancy, age 49.She has had 5 children and 0 living.In their household is Gussie (?) H. Floyd, nephew, age 29, single.Can anyone tell me anything about his wife Nancy.(I believe her maiden name is Henderson.)Nancy Victoria Henderson lived in the household of Avery and Pennie Floyd in 1870 and 1880.John J. and Nancy Floyd are also in the 1900 Floyd's Township of Horry Co., SC, but it is difficult to read because it is so dark and is at the bottom of the page. If this family has been researched by anyone, and my hunch is correct, I will be more than happy to give you a background on her ancestors back to 1767.Thanks for any help.
