I have been doing some research for a Hodge Brooks family originally from Kingskerswell Devon. i think they are descended from the same Mary Brooks as you have on your tree. They are definitely descended from Harry Hodge Brooks whose parents were William Hodge Brooks and Elizabeth Ann who keep the Half Way House Inn in Kingskerswell for many years (1891-1911). As far as I know William's father was George Hodge Brooks a farmer in Kingskerswell. I think George's father was John Hodge (a fishmonger) and George was originally called Hodge (1841 census). Mary Brooks (also a fish monger) lived with the Hodge family and then by 1851 John 'disappeared' (maybe he died or moved away) and Mary was living with the Hodge children. It seems that the family then became known as Hodge Brooks.
I hope this helps
