Hi again Lin
I had a little think this evening and thought I would look to see if anybody else in the censuses (on Ancestry) also had a first name similar to Pockrage/Pockridge and strangely enough I found no-one! That leads me to wonder whether the name Pockrage[+variations] was originally used as a surname. (People could inherit surnames of their close / not so distant ancestors as first names).
So I had a look for Pockrage[+variations] as a surname and I just got the one result, funnily enough in county Armagh Ireland (the area I mentioned in my other reply to you this morning). So here are the details, and if no use to you in their own merit at least they prove the was a family with that surname in Armagh.
Index of Irish marriages 1771-1812
On page 360:
Miss Pockeridge married Jonathan Seaver in 1787 (ref 560)
On page 397:
Seaver, Jonathan, Herthall, co. Armagh = Pockeridge, Miss nr Monaghan Oct 1787 (ref 560)
p.s. that is all there is in the index and I cannot advise any further steps to follow unfortunately.
