Never go by what someone said on a website. It is not documented and no I was not being rude.
A good genealogist always says "show me the document.
There were no twins. Like I said which would you believe
(1) something someone threw out there or
(2) U S Federal Census
(3) family bible info.
(4) family traditon

I am not related to this Line ok. But I have a friend and business assoc. who is a Direct descendant and he has family records.
I only know the 1877 child was called Callie.

I can go pull up probably 20 family trees on the net of this Hardin and find numerous ones that came from who knows where. That is the problem with the net. Many people throw things out without first verifying the data.

I guess I seemed rude to you but I have been doing this for many years, am a published auther in Genealogy and Western History.

Finally, I do not find a Jane martian Hardin that is verified. Like I said if you have proof, not say so please inlighten me friend.
