I think I might be able to help.
I missed this message because I had already answered the original to the thread.
But you have introduced new information.
I note the other answer you have received which adds useful information, but in addition, it is likely that Mabel Audrey had a brother named John Harris Ivens (1908-1988) and another called Arthur Stanford Ivens (1899-1979) a grocer.
I am in contact with descendants of both of these people.
In addition, Edward's father was Richard Ivens (1807-1845) married to Elizabeth, sister of Anna Maria who married Richard's brother Edmund, a butcher in Leigthorne, Warwickshire.
There are at least another 6 siblings to Richard and Edmund, and I have some of their tree, and am in touch with a further3 descendants.
It seems your husband has distant cousins all over the place.
Do get in touch to help fill in the blanks, and to let me share what I have with you.
