Looking for Information on David Bloomfield

My ggggreat grandfather settled in New Brunswick and was given a land grant due to the fact he was in the New Jersey Volunteers and was an Empire Loyalist.
He married Patience Wayman/Weyman and died in 1800 in New Brunswick. His wife remarried.
My question how old was he?
Where did he originate from New Jersey?
Who were his parents?
