The elusive James Taylor

I had a brainwave, maybe James died about the time of the birth of William Greathead and Sarah Brown's second child. Hence her announcing her previous name. So before the cost of certificates went up I ordered four possibles. 1855/Q4 Teesdale, 10a-69. 1852/Q2 Darlington 10a-8, 1854/Q2 Houghton le S 10a-154 and 1855/Q4 Easington 10a-140.

Sadly none of these can be the correct one.

Ho hum, back to the drawing board and that brickwall!!
