TheSouth Londonderry constituency for theParliament of Northern Ireland was created in 1929 and continued until the abolition of the Parliament in 1973. All members for the constituency were from the Chichester-Clark family: the first was both the son-in-law of the second and the father of the third.

Dehra Parker had been elected (as Dehra Chichester) forCounty Londonderry in the 1921 and 1925 elections under thesingle transferable vote; she became a Dame before the 1953 election. Her grandsonJames Dawson Chichester-Clark wasPrime Minister of Northern Ireland from 1969–1971 and after his resignation was created Baron Moyola in 1971.
