Hi back again with some good news and some bad! Bad is that I couldnt find a Dinah Maynard at all, the good news is that Charles Riley Maynard had 2 daughters Agnes( 1884) and Frances Mabel(1892).After re-reading the excellent download of the history of Maynards, only Mabel is mentioned, so there isnt much more I can add. There was several Frances M Maynards in the records of marriages as well as a death in Chichester in 1982.
Its possible that the photo is of Frances, and funnily enough my mothers name was Mabel (1911). Could she have been named after her as it seems she prefered to be called Mabel instead of Frances.The Maymards tended to use their second name. Charles Gordon, Joseph Douglas were two. I think the other photo is of either Charles Riley or his son Chas Gordon. I found the family in the1891 to 1911 censuses. Before that Chas Riley was living with his father Riley and mother Ann. According to the History, his brother Tom had little to do with the business and moved to South Africa. As far as I can tell they didnt have any shops in Weymouth, but in Brighton and around that area. Hope thats been of some help
