Edward SNOW, June 1786-Sept 1851 and Jane GALLISHEN?, 1795?-July 1837

Interested in reaching out to others who are related to this couple who married Dec. 31, 1812 in the Cathedral of St. John the Baptist, St. John’s, Newfoundland. Witnesses were Clement POLLE (might this be POOLE?), John GALLISHEN (sp?), Mary JAHI (can’t find others with this surname) and Mary CARROLL.
Two of their children were Sarah SNOW, born June 28, 1818 (who may be the Sarah SNOW here-Nov 8 1838 John PEACH, bach, Chippinhow?, Dorset & Sarah SNOW, spin, St Johns
WIT: Anne AYLESBURY, Joseph GATES
At St John’s Anglican Cathedral of St John the Baptist)
and my ancestor Henry SNOW, born May 15, 1826, St. John’s.
Henry SNOW married Jane CUMMINGS (might this be the same as CUMMINS?), May 15, 1826, in St. John’s at the Cathedral of St. John the Baptist. Witnesses were William GEORGE, George FILMER (FILMORE?), John TAPPER, Mary SNOW (wish I knew who she was) and Elizabeth SNOW (also of great interest to me). Edward Joseph SNOW was their son.
Other offspring of Henry and Jane SNOW were George CUMMINGS SNOW, Feb 1856, William Thomas SNOW, 1858-1859 and John SNOW, born March 15, 1861 in St. John’s. Thank you. hlgoebel@yahoo.com
