Yes that's the family. I have just realised I had a previous topic on this a few years ago and forgot about it.
I think I have just found Edith. death reg. June qtr 1875 Lewes(Sussex) aged 15. That is where Mary Ann married Thomas Stoner in Sussex in 1876.
On that other topic(Richard Mansell burial Wiltshire) Trish did find Edith Mansell bapt. 21/7/1861 St Brides Minor, Glamorgan parents Richard and Elizabeth although I have never found a birth for her.
