Lokking for Mee Bruce Family from Blackheath London Area

My grandfather was Reginald Leonard Mee(1911-1996) and he married an Edith Maude Bruce (1910-1973) in 1938.

I am having trouble determining the parents of Edith. They appear to be Ernest James Bruce (1871) and Florence Minas Bruce (1873) and they were married on 29/9/1896. HOWEVER there is also a connection with a Florence Beatrice Bruce/Mee. In later years the electoral rolls at 28/30 Lewisham Road show Ernest James Bruce with Florence Beatrice Bruce, and Reginald and Edith Mee.

Am I getting muddled or could Ernest and Florence Minas have divorced and then Ernest remarried Florence Beatrice Mee ( or I would imagine had been some sort of blood relative to my grandfather.

All looks a bit messy. I would greatly appreciate any advice/help
