George Dray, Gillingham, Kent (b. abt 1774)

I'm interested in George Dray of Gillingham, Kent who was born about 1774 (place not known) and who died in Greenwich, Kent on 4 Sep 1837. He married Elizabeth CONEY at Gillingham, Kent on 11 Jun 1797.

Known children:
George William Dray (b.1798 – d.1853)
Elizabeth Dray (b.1800 – d. 1868)
Mary Dray (b.1802 – d. ?)
Mary Ann Dray (b.1804 – d. 1822)
James Henry Dray (b. 1810 – d. ?)
Joseph Dray (b.1814 – d.1829)

I'd be interested in anybody who could shed light on where George Dray (b. abt 1774) might have come from as his baptism is missing from the Gillingham parish registers (and those of surrounding parishes) and of course any of his parentage. Thanks.
