To AJ100, I have two Marsh lines in my family, would be interested to know what you have.
JOHNYP, this from Kent Parish Records, Family Search and what was passed onto me by a Finnis family member.
John Finnis baptized 25th April 1759, died 1824, buried 17th July 1824 St George's Deal.
He married Mercy Belsey daughter of John Belsey, Yeoman of Northbourne 25th February 1785 Deal. John was a butcher.
I have Mercy baptised 16th Feb 1752 St Leonard's Deal, but this needs checking.
From then on Belsey was used as a second name for all the John Finnis' to come plus for other family members.
John and Mercy had two sons.
John Belsey Finnis 1786-1852 my line
William 1788. Baptized 23rd February 1788 St Leonard's Deal.
William m Jane Dawe (Dawes) but can't find a marriage date.
They had 4 children,
Henry Belsey Finnis 1810-1855 a gatehouse keeper at West India docks Limehouse.
The thing that puzzles me is Hythe as birth/baptism place, can't link that with Jane or William. The three daughters were
Ann Belsey Finnis 1811-1821 bap 1st Jan 1812 bur St George's Deal 16th April 1821 of Beach St.
Jane Mercy Finnis 1814 bap 12th June 1814 Deal
Elizabeth Dawe Finnis 1817 bap 30th July 1817 Deal.
William was recorded as baker of Oak St Deal on baptism records.
Jane possibly died 1834. Record of St George's shows a Jane Finnis buried 18th March of Beach St.
Found in Pigot's directory 1839 a William Finnis baker of 109 Beach St Deal. He wasn't listed in the Bagshaw's of 1847.
Hope this helps.
