Hi, I wasn't sure there was any connection but since we are both searching the same surname, I thought I'd at least reply. I posted looking for more info on the Cumberland forum and got replies with 1841 & 1851 census info, it appears (as I suspected?) that John was born in SCT.
Here's my query from there, if any of it helps at all, never know......

Looking for any information on "my" Robert Aitkin christened 1809 Dalston,CUM and his wife Ann(e)(maiden possibly Ruddick)born Talkin (1851 census)children: Emma,born ca.1841 Newcastle,NBL; Marie born ca 184_ Gateshead,DUR;Robert born ca. 1847/8 Gateshead,DUR.;Jane E. born ca. 1850 Gateshead,DUR.
