There's a bit on the history of the scout hut near the bottom of this -
Scouting in Upton. The original hut was one of those built in Arrowe Park for Baden-Powell's Scout Jamboree in 1929. Presumably the hall Granny's mum went to would be the concrete structure mentioned as being built in 1952.
The Houghton connection could come from the Houghton family who were local landowners - the Cheshire Tithe map shows several parcels of land in the Upton area being owned in the mid-19th century by one William Houghton, who it would appear lived in a house on the corner of Salacre Lane and Ford Road, shown as the smallest yellow area in the centre of the map here -
