Hi! Taking a quick look in my family tree and I have Samuel!
Samuel Leeson 1746 - 1808 Birth and Death Newnham
Married Sarah Elizabeth Whiting 31/10/1771 Newnham
His father I think was Thomas
His son I have as Charles Leeson B1783 Newnham who married Ann
They had Henry and Elizabeth in Braunston 1818 and 1826 respectively
haven't so far found any siblings for Samuel though
