I also have POUNDERs who originated in Middleton Tyas in the late 18th Century, we don't know where the parents were born, married or were buried. My ones went to Kirkbymoorside > Stokesley > Lambeth > Bolton.
My earliest Hammond was a soldier in the 68th (Durham) Regiment of Foot (Light Infantry) in Canada though he was almost certainly from Yorkshire. He married my Great Great Grandmother in Quebec in 1844, had one son there just before returning to England. They had a daughter, my Great Grandmother, in Chester in 1846 just before the regiment went to Dublin. I am trying to find what happened to him after that.
