I’ve done a bit more digging and found a report into the inquest of Mr Hargreave’s death in the Liverpool Echo dated 28/1/1952 (page 6) As it’s a subscription service I can’t link to it and I’m unable to get a good screenshot either. You may already be aware, but his middle name was Moses.

Hi Stuart, I’m into family history so thought I’d have a quick look on a website I’m subscribed to. I’ve found a burial record for a William Hargreaves aged 66 in 1952. It is for Pleasington Priory, St Mary and St John the Baptist, grave F.A12 and has Roman Catholic as this gentleman’s denomination. I’m not local so don’t know if this is the right place, but I thought I’d share it in case Hope this helps
