John Palmer (b. 1777) married Esther Collins, daughter of Benjamin Collins and Mary Heamer, at St. John the Baptist Church, Winchester (The Oldest Parish Church in Winchester) on 26 Aug 1811. 

(Esther Collins was baptised on 15 Aug 1790 at St Bartholomew's Church, Winchester, where her parents had married on 30 May 1789.)

John and Esther Palmer, it seems, had at least these four children:

1. Charles Palmer b. 12 Jul 1812, bap. 24 Jul 1812 at St Mary's Church, Hinckley, Leicestershire. As unlikely as that location seems, on the 1851 census, Charles' birthplace is listed as Ionkley, Lancashire, which could be a mis-transcription of Hinckley, Leicestershire. 
2. James Palmer bap. 16 Sep 1821 at St Andrew's Church, Plymouth
3. Elizabeth Palmer bap. 25 Nov 1827 at St Andrew's Church, Plymouth
4. Henry Palmer bap. 18 Jul 1830 at St Andrew's Church, Plymouth

On James', Elizabeth's and Henry's baptisms, John's occupation is Tanner.

It's extremely likely there were other children born between those, but it's difficult to confirm, not knowing when or where and being too early for them appear on census returns for confirmation. 

In 1841, John Palmer (60) was living in York Street, Plymouth (as was son Charles, in a separate household), with Esther Palmer (50), Elizabeth Palmer (14) and Henry Palmer (11). There is a James Palmer (20), resident at Plymouth Citadel, in 1841, but I cannot be absolutely sure.

In 1851, John Palmer (75) Tanner, from Bridestowe, Devonshire was living in Richmond Street, Plymouth with wife, Esther Palmer (61), from Winchester, Hampshire.

John Palmer died, aged 78, in 1855 M Quarter in PLYMOUTH Volume 05B Page 251. He is buried at Ford Park Cemetery, Plymouth.

In 1861, Esther Talmer (sic) Tanner's mother, widowed, from Winchester, Hampshire, was living in Vauxhall Street, Plymouth in the household of her son Charles - who it appears has taken over the trade from his father.

Esther Palmer died, aged 79, in 1868 J Quarter in PLYMOUTH Volume 05B Page 145. She is also buried at Ford Park Cemetery, Plymouth.
