I have found my great grandparents on the 1911 census
William Edward Andrews (1871) and Hannah Andrews (1877) living in Shepperton, Middlesex with Hannah's mother Ann Grout (1847).
At this time I know they had at least two children that were still alive (census form states this) -one was my Uncle Percy. Neither children are listed with them on the census, and I can find no trace of Percy anywhere. I have no idea who the other child was.

Any help in finding Percy and the other child much appreciated.
Percy was born 23.10.1902 in Gartbrook, Betchworth, Surrey, England (I have the birth certificate).
Thanks in advance
