Hi and welcome to Rootschat
What country are we looking at here as there is no 1979 death for a Richard Boswell and no Boswell/Sparrow marriage or births. The way in which you write their birth and death dates is not the English way so I suspect a different country than England
The only Richard Boswell birth is this one but if he was born in January - I would have expected to see it in the March quarter
Births June qtr 1917
Richard Boswell mothers maiden name Harman Croydon 2a 565
