Hi George
I'm not sure if this will be of any help to you but Scotsbridge House is situated on Scots Hill, Croxley Green.
Croxley is between Watford & Rickmansworth. There is a Parish Church, All Saints, but as it has no burial ground most of the inhabitants of Croxley were buried at Rickmansworth cemetery, Chorleywood Road, Rickmansworth.
From Free BMD there is a death of Amy Hooper June qtr 1912 Watford 3a 726. Could father & daughter be buried together, I wonder.
It might be worth you contacting Three Rivers Council, Rickmansworth, they may be able to help you in locating the grave/s
Hope this helps in some way.
