Thanks redtonyt.
Looks like this William is one of them.
However the one I really want to confirm is the one born in 1800. At the moment I believe him to be recorded at St Mary's Dover as the son of William Finch and Susanna.
Finch was William’s Fathers name and the St. Marys, Dover record (2nd March 1800) of the christening of William son of William Finch and Sussanna, I believe refers to Susanna Matson (1780-1856) who later married a William Doves in 1803.
Matson was his Mothers name. He was brought up as Matson and added Finch when he was told who his father was.
Tithes for Alkham (1830s/1840s) show William Matson as a tenant farmer of Peter Lane Fector. Also William Finch as Owner Occupier of nearby Malmains Farm.
The Finch family was near neighbours of the Matsons. William Matson and William Finch had nearby farms at Barham and Alkham. The Will of George Finch of Dover, gent. dated 26th May 1684 (probate 3rd November 1684) refers to “Friend John Matson the younger of Dover”.
The marriage record of 1803 records William Doves of Buckland and Susan Matson spinster of this parish (e.g. Whitfield).
The 1841 census shows Sarah Doves as a 60-year-old Grazier and having 4 Matson children, Alice (11), William (
, Jane (5) and George (3) living with her.
The 1851 census shows Susanna Doves, a widow aged 73, living next door to the William Matson family at Drelingore. With Susanna are 3 Matson grandchildren. Alice, Jno (John) and Mary. There is also a William Hills a 69 -year-old widower who is recorded as a Servant with occupation Labourer and born Alkham.
No record found in 1861 census or of any Dove(s) at Guston in 1841 census.
There are other records which seem to confirm this William Finch Matson as the illegitimate son of William Finch and Susanna Matson but I'll probably never know for certain.
