OK, so all my family lines are from London and the Southeast; but I always knew that sooner or later the Martindale line was likely to drag me up to Cumbria. Now I believe it has.
I believe that the migrant was John Martindale, a Quaker, who married Martha Taylor at Horsleydown meeting house in Southwark on 31 May 1694.
He is described as John Martindale of Aldgate Parish London Tobacconist, son of John Martindale of Newchurch Parish in the County of Cumberland Farmer Deceased.
It's the father, John Martindale of Newchurch Parish in the County of Cumberland deceased who interests me. Obviously, he must have died before 31 May 1694 .... but I have no idea how much before; and I am not having any joy in tracing any record of him at all in the online search tools.
I will be most grateful for any scraps of information that you may be able to turn up.
