JA,
I remember a Mullarky family in Bebside Colliery (either in Front Street, high even numbers and/or Bebside Furnace) We were rehoused from there to Weardale Avenue in about 1951.
Just to show off, our St Cuthbert's at Cowpen predates St Wilfred's Blyth, by about 20 yrs.
I have full list of St Cuthbert's confirmations, including Bedlington folk, before St Bede's did their own.
