James William Arkins or John Arkins???

I was hoping that someone could provide some information concerning either James William Arkins or John Arkins. My grandfather, James William Arkins, was adopted by his Aunt, Leah Arkins and her husband James William Arkins.His birth mother's married name was Catherine Krever.The biological father listed on the adoption papers is Alonzo Jackson. If you have any info on this matter, I would love to hear from you.
