Your Thomas Addison & My Thomas Addison, are 2 different people. I know, it gets confusing. As far as the Addisons, from other states, to Indiana, I have not a clue to the number, only know alot of them did. But I am pretty sure all the Addison's in Henry, Rush, Shelby & Hancock counties, in Ind. are related, by way of Virginia, North Carolina, South Carolina, Maryland, England. and maybe Kentucky.
