Hi Janey,
I found the following - maybe they will be of some relevance:
Middlesex Parish Registers- marriages - V. Edited by Gurney
Harefield marriages
vol 1 Thos Goodman & Elizabeth Walker 3 June 1576
Nicolas Coper & Anne Collett 7 May 1668
vol V Jas Goodman,w.,&Ann Fisher,w 8 Aug 1830
Jas Tibbles & Harriet Goodman 14 Feb 1836
Rich Collett & Sarah Bolton 25 Dec 1837
There is an excellent book `Ickenham & Harefield Past`by
Eileen M. Bowlt, which tells of a serious incident involving
some gypsies who `nearly killed R. Collett, Mr Speddings groom`, and also a photo of Cumberland House which was built by the Colletts as a family house and became the vcarage in 1927 - now, sadly, no longer standing.
In 1858 Henry GOODMAN left £500 for flour, raisins and beer for 50 families.
In 1901 David COLLETT (local builder) bought 11 acres of land to the east of Rickmansworth Rd. The Collett family (or the Collett trust as I hear them refered to) still, I believe, own many properties in the village.
Haven`t been able to look for 148 High Street - will post when I have.
It might be worth contacting the Hillingdon Family History Society for info on William COLLETT and George GOODMAN - sorry I didn`t find anything this time.
I hope some of this is of interest to you - I enjoyed learning some more of my local history! Please let me know if you need any further look ups - I am a member of the Hillingdon Family History Society and go there fairly often.
