Maggie, I have only just come across this message, so you probably know all this already. Stephen seems to have died in 1856, followed shortly by his sons. George died in Apr-Jun 1861 (Marlborough 5a 47) or Jan-Mar 1862 (Marlborough 5a 50). Henry appears to have died in Jul-Sep 1862 (Marlborough 5a 39).
Do you have any more info about George Eatwell, Stephen's father? There are so many George Eatwells around Winterbourne Bassett at this time that it is difficult to find how they slot into the tree.
My wife's mother is an Eatwell, descended from William Eatwell b.~1800, I think.
