Spoke to one of my Aunts today and she thought the estate belonged to a Sir Mark Ediman Collet son of Sir Mark Wilk Collet (1864-1944) First Baronet of St Clere's born 1816, died 1905, a Governor of the Bank of England.
I was also a bit confused with the dates that my Great Grandfather lived in Old Terry's Lodge. He worked there during the twenties and thirties which is where my Grandmother and her siblings grew up but they had moved on to Fairseat by the forties til the seventies to another estate owned by the Stonehams I think which is the cottage I remember visiting.
I do remember my Gran saying how she used to be allowed a ride on the masters carriage up to the main house (St Clere's?) sometimes , when she was a small girl and having to walk three miles each way to school in Wrotham.
Anyhow I am speaking with my Gran's sister in law soon who would certainly remember more so hopefully will report back soon.
Regards and have enjoyed opening up more of my families history in that area, thank you.
