According to H.F.Tebb's book Dogsthorpe Manor was originally a Grange for the Abbey. Following the dissolution of the Monasteries in 1538, Doddesthorpe became the property of the Dean and Chapter of Peterborough Cathedral.
The manor was bought by William Fitzwilliam in 1578. It was sold again in 1633 by the grandson, also William Fitzwilliam. However the article on Dogsthorpe Grange suggests that the Grange and not the Manor may have been William Fitzwilliam's home.
During the Second World War Manor Farm was owned by Mr Odam. www.westwoodworks.net Tells how the 2nd Battalion Northamptonshire Regiment Home Guard had its headquarters at Manor Farm, Dogsthorpe - the home of Mr. Odam - the Home Guard being allowed the use of his barn in inclement weather. However whilst looking at a 1970's Ordnance Survey Map I notice there is a Manor Farm off Newborough Road, where the A15 Paston Parkway now goes. So perhaps this is the Manor Farm referred to not The Manor in Dogsthorpe.
In 1962/3 there was still a farm in Welland Road, where Dovecote Close now stands. My mother who moved to Welland Road in 1958 remembers taking me to look at the pigs. The third photo down of Welland Rd has the gable end of a large house on the right hand side of the road, this could well be the 16C Manor, the line of the roof and chimney are the same as the photo in H.F.Tebb's book. This page has a larger version of the same image
There is now a Victorian style building called The Manor at 10 Welland Rd, which is Stepping Stones Nursery, however I am sure this is not the original Manor, as the angle of the roof in the photograph in H.F.Tebb's book is wrong for it to be the newer building.
This photo may also be the Manor, with a new roof minus the dorma windows it would be very similar to the later photo, and the location is right.
