All born in County
As the only census Robert seems to appear on is the 1861 and only John 1846 +Lavinia 1859 are born in England. Roberts Wife Joannah who is born Scotland means they may have Married anywhere.
As this has Robert born c 1811, Charlinch is may be incorrect as he has a much younger Wife he may have dropped his age a little!
Lavinia Lanseys 1859 Birth Cert will reveal Joannahs Maiden name (if you do not already have it)
Then the Marriage to Joannah may be able to be found which will hopefully have his Fathers name and occp on it.
Burial;
John LANSEY, 29 August 1844, Over Stowey, Somerset, Age 76 (Birth 1768)
