My Gt.grandfather's marriage cert says he was born in Boston, MA, c1833, son of Frank Adams (storekeeper) and Matilda Stephens. He joined the British Army (supposedly the Royal Engineers), was a champion with the short stick and was supposed to have served in India. He was married in Australia in 1858, and married for a second time in New Zealand in 1871. He had a large family but left his wife in 1883 and was never heard from again. Have searched all the Boston records I could find but no George. Can anyone help?
