I do have the marriage certificate of John. He married in 15th July 1834. St James Westminster. Its a short version so theres no name of his father.
He and Ann were married by banns but I've searched the church records of St James, also the church at Old Windsor where Annes parents were living at that time. John and Ann had a daughter Maria born in 1839 in Finchley, London I've searched church records there for the Banns but no luck.
I have written to all the people with family with the surname of Forrest who were born around 1800 on Genes Connected to see if they had a relative with a sibling John.
On the IGI a lot of Forrest"s came from Scotland.
I have a death cert of one of John's sons which showed that he had the name of Joseph Frost Forrest. Thats how I know that the change of surname hadnt been misspelling on any church record.
Joseph Frost Forrest died at Birch Green, Hertingfordbury in 1839.
John was a coachman when his son George was born.
My ggg grand father (registered)George William Benzey Forrest (son of John) was born in Egham Surrey in 1841 but wasnt christened until Apr 1847 St Mary's Portsea, Hants. Thats where the surname changes to Frost.
(I have checked the church records and its also on the IGI).
The same applies to Georges sister Maria Forrest. She was born in Finchley, London in 1839 but in Jan 1847 (the same year as George) she was christened at Kingston, Portsea Church, Portsea. as Maria Frost
George died in Portsmouth in1917.
There are several other address's I have of George, Marylebone, Mile End Old Town, He worked several jobs a Butler, footman, commercial traveller
I could go on and on but no John Forrest/Frost birth place.
This morning I wrote to the Westminster Archives to find out if they have any more information on him as he died in The Workhouse, Mount Street, St George, Hanover Sq.
Ive been running out of ideas but cant give up.
