In that case, Mark Burry was baptised 10 May 1857, born on Newell's Island to parents John and Sarah.
I don't think I have access to Mark's marriage record.
John Burry married Sarah Stark on 7 Nov 1844. (St. Stephen's marriage records) Their other children born on Newell's Island: * Henry (bap 1 Dec 1850) * Mary (bap 23 Jan 1853) * Robert (bap 8 Jul 1855) * Alpheus? (bap 22 Feb 1860) * Abraham (bap 20 Sep 1863) (St. Stephen's baptism records)
John was buried 1 Apr 1860 at age 65 (b~1795). (St. Stephen's burial records)
