Internet says ... Until the early 20th century the village was dominated by three estates, the owners of whom were the Duke of Northumberland, the Bedlington family and the Bigge family.
https://communities.northumberland.gov.uk/Ovingham.htmWith George Snowball moving about within the Parish of Ovingham (to have their children), it sounds like he might be working for the Landowner/s?
Some Landowners were Nonconformists, a few had their own Chapel or supported a Nonconformist Meeting place.
If Snowball didn't own his dwelling ...
Have you seen any of the Landowner records (including the Manor of Ovingham), especially Landowners Tenantry lists? For example Landowners Surveys, yearly Rentals or Accounts (if they have survived) of the Landowners and when Snowball first appears. Occasionally, if they took over the Rental of a property or plot, the previous Occupier is mentioned (around the take-over years). These might be relatives or even their Father.
Landowner records might look similar to Land Tax records, but Land Tax records only deal with Lands actually subject to Land Tax. Whereas Landowners usually include all Renting from the Landowner.
It would be unfortunate though, if Snowball rented from a person who owned a handful of properties and not one of the main Landowners.
