Gibson question

I have figured out my family line of Gibson, after a long search and getting my great great grandfather Tyre Gibon’s death certificate. He was the son of Squire Gibson b.1925, but he has Nora Harrison listed as his mother all I see is Perlina as Squires wife.

My question also is I have read many threads on here about Gibson’s and seen that it was stated that they do have Indian heritage, can anyone answer who they believe the Indian came from?

Laslty if there are any lurkers on here still researching the Gibson line my last mystery is Tyre’s wife Martha (Patsy) who her parents were, I was told her last name was Phillips any help on this would be great!

Thanks
