funny, i dont know where you got the information for the first paragraph, but that was from my grandmothers own research that i have.
from what i have, Martha Hobbs died 14 nov. 1864 and i do not have a listing for another wife inbetween here and Elizabeth (Lucienda).
Martha Fransics Hobbs Davidson is the daughter of Elizabeth and John Hobbs according to the research my grandmother did 20 years ago. I even have a photo of her and she looks like a native american. This is my family line, I will have to call my grandmother tomorrow and ask her about the birth of Martha and the Marriage. but everything i have states that Martha f. was born before her parents were married. I have much more information on this line of the family if you are needing it.
be careful when researching this line. my grandmother stated several times in her notes that there were three john hobbs living in cape at the same time. there was even a john hobbs, not related to our john hobbs, living on the street behind ours. she said it took her awhile to figure out what john was our john.
also the john hobbs listed in the 1880 census was her son. he was born in1870. there was also a james penn living in the household.
my grandmother said that john and martha had at least 7 children but only 6 were listed in the 1860 census. at first i thought maybe the other martha was their child, but it couldnt be since martha penn hobbs died in 1864.
also elizabeth was married before john and had at least two children with james randol.
let me know if you have any questions.
right now im trying to trace john hobbs fathers name. there are some misunderstanding to who it was. i was hoping by tracing a different line back that i would come across some information to help me with this line as well.
