Recorded in his son's marriage entry in Coleraine Registry Office, this may be the same John Brewster from Glenhall who is recorded in the 1795 Flax Premium's List and it may be the John Brewster who is buried at Camus graveyard - although he appears to be a little young to be either of these.
He may also be the John Brewster who appears in the TAB holding 8/1/3 acres. And he could be the John Brewster who heads a household of three males, one female and a servant on the 1831 census.
Or, this man might be the son of the John Brewster in the 1831 census, who may be the man who is buried in Camus.
A James and a John Brewster, both of Glenhall, were appoined cess collectors in Glenhall by the Vestry Committee of St. Mary's Parish Church in Macosquin in circa 1807 (very circa as there was no date and this was the next date mentioned).
