Apart from this monument, the church contains marble ovals to the memory of Matthew Flinders' father, grandfather, and great-grandfather.

They were provided from a sum of 100 pounds left by the navigator, in his will, for the purpose.
It is interesting to notice that three of the early Australian explorers came from Lincolnshire, and were all born at places visible in clear weather from the tower of St.Botolph's Church at Boston.

While Flinders sprang from Donington, George Bass, who co-operated with him in his first discoveries, was born at Aswarby, near Sleaford, and Sir John Franklin, who sailed with him in the Investigator, and was subsequently to become an Australian Governor and to achieve a pathetic immortality in another field of exploration, entered the world at Spilsby.

Sir Joseph Banks, the botanist of Cook's first voyage, Flinders' steadfast friend, and the earliest potent advocate of Australian colonisation, though not actually born in Lincolnshire, was the son of a squire who at the time of his birth owned Revesby Abbey, which is within a short ride of each of the places just named..
