No... I had a look. ...all I left out was that Mrs W.R.Filby was a domestic, and she was British.
I tried to find the birth in 1911 of the boy but couldn't. ...Out of curiosity, though, I tried the census for 1911, just typing in Filby and for residence:Kent. TWENTY SEVEN Filbys came up, most of them living in Bromley.
Suggest that you could also try this to see if any of the first names might be familiar to you....
