Hi,
According to the listing the existing ' Rising Sun' pub was originally a Miners Welfare Institute built in 1908, bought by Tetleys in 1948 as replacement for original Rising Sun pub. The current building is a grade 2 listed, as is the adjoining terrace of cottages, and was designed by CFA Voysey for the Briggs family. When I lived in Castleford they had the distinction of being the only listed buildings in Castleford - I'm saying nothing else

!!
It would seem from this information that the pub that your family ran may well have been the original 'Rising Sun' which appears, according to this information, to have been a different building,
If you want a photo of the current 'Rising Sun' there is one on Flickr.
