Where was Hollydale, Waverley Road, Weybridge?In the 1901 census there are two households listed at Hollydale: the Grant family; and an Elizabeth Robinson, widow, with her daughter and grandson. In 1911 the situation is similar: the Grants at Hollydale with their neighbour Elizabeth Robinson next door, also Hollydale.
I have found these properties in the 1910 Valuation records. The details of the Grant residence are:
Waverley Road, Cottage and Garden
occupier: Grant
owner: E Robinson, 1 Hollydale, Waverley Road, freeholder
weekly tenancy
annual rent £20 16s [=8s per week, there is an annotation that this seems low, should be valued at 9s]
3 Bedrooms, Parlour, Kitchen, Scullery
Coals, Pantry, & W.C. — good
brick slate — good
This property and Mrs Robinson's are a pair of semi-detached cottages, presumably referred to at that time as 1 and 2 Hollydale. The associated maps show clearly that these correspond today to nos. 4 and 6 Waverley Road. I was all set to post an image, forgetting that this is a lookup thread, no images allowed. So, you will have to go on to streetview and find it for yourself: no. 6 corresponds to the Grant house and is at the north end of the street, on the east side.
Finally, unless John Grant ran a gardening business and was employing others (there is no evidence for this), I don't think he would be considered to be lower middle class; rather he was skilled working class. In the 1911 census he is classified as 'worker'.
