Family name of Stanborough, Stanbrough, or Stanbro

I stared researching the Stanbrough name about 8 mos. ago. I started with Jonh Stanbro, my gggranfather. He lived in Indiana and was married to Lydia. They had 13 children. I wrote letters to all the Stanbrough's I could find in the "white pages" on the internet. Received a lot of beneficial information from people around the country. I now believe our name goes back to Stanborough(Josiah), who entere this country from England in the 1630's. Any information anyone has that will help me with my reserch would be appreciated. Thank you.
