Hello Janet, if the entry was transcribed as " Newcastle Lynn " there are a few possibilities - (i) "Lynn" was a misreading of Tyne, and - (ii) "Lynn" was a misreading of Lyme from Newcastle under Lyme which is a completely different town, in Staffordshire in the Midlands. (ii) there is also a Newcastle Emlyn in Camarthenshire in Wales. Are you sure your g g grandmother was from the North East? Jennifer
