In 1871 they were at Kelvington House, St Mary’s Cray, Kent but there was no assmbled transcript of the household,

In 1981 they were still at Kelvington with an enormous household; Herbert and Cecil were missing but Maud, Edward and Atherton and Violet had been added:

_________________________

In 1891 Herbert and Cecil were back at home and there were no more children after Violet.  But now the missing were:
Richard
George
Edward
So we have 8 children in all, all born at St Mary Cray.  It will be valuable to compare this with what can be found on the birth records.  What I am expecting is to find is a few infant deaths.

In the 1911 census it was reported for Fanny that she had been married for 50 years, had had 9 children of whom 6 were alive and three had died.  Luckily this is confirmed by the following list of births found onthe birth indices.

The birth registration search brings in an earlier Richard, born in 1863.  So the son born in 1864 was named Richard as well. All the births were in the Bromley district. The latest list is:

1. Richard         1863
2. Richard         1864
3. George          1866
4. Herbert         1867
5. Cecil           1869
6. Maud Catherine  1871
7. Edward          1873
8. Atherton        1877
9. Violet Frances  1860
