Post 1922 BMD Records?

[Abygail]

Apart from the PRONI is there another source of BMD records post 1922? and if so how far forward do they come?   I'm hoping to find info re GGGP's and hopefully some of the children (as senior adults) late 1940's early 1950's from Glencon Co Tyrone and Armagh maybe early 1960's.
George and Mary Seeton died c1924? post 1922 anyway
Thomas and sister Sarah Jane Seeton late 1940's
and their nephew, Hugh Seeton who I think died very close to Armagh c early 1960's.   There was another married brother of Thomas's, James Seeton, have no idea re wife's name or potential offspring, or possible dates.
