Hi
you are welcome.
I reread your initial post and realised I made a mistake too, I have a brain injury so can't keep much information in my brain.
With the one off payment, if we consider the age our ancestors lived to in the UK, they were young when they passed, the one off payment may have been taken to give to his daughter, because in his demise, they would receive nothing. Most took the opportunity for support - one off payment, mine moved to a new country because their lives were so difficult back then.
There are some incredible books online for the 41st, with specific year ranges, you may find some information about him in one of the books too xx
