Hi lila,
Regarding the Vickers from Towlaw.
From what i know all of the Vickers in that area originally came from the up the Wolsingham, Stanhope valley.
I haven't heard of a Pea farm in Towlaw and the weather up there wouldn't be the best for growing peas.
Could it be Pease farm?
I'm pretty sure that there was families with the surname Pease in the Towlaw, Wolsingham, Stanhope area and would have been related to the Vickers.
regards,
Rewcastle
