Name, year of marriage of 1919, from Simon Perry in an email dated 9 August 2022. Simon is the great-grandson of this Edgar Joseph LOBB. Simon is also the great-grandson of Ernest Henry GRAY and Frances Maud ANDREWS.

Brian of nzolivers wonders if this “Rita Cottier” is the same "Rita May Cowling Cottier”, born in 1899, who is the granddaughter of Mary Jane Grylls?
Mary Jane GRYLLS is the sister to the Richard GRYLLS already in my tree:

Richard GRYLLS married Sophia OLIVER, granddaughter of James and Ruth OLIVER.

If this “Rita Cottier” is the same "Rita May Cowling Cottier”, then the tree would look like this:
