Hi,
Did you find an early map of Wythenshawe, as I have a couple
The best book to get for the time period you have is called:
Wythenshawe A History of the Township of Northenden, Northen Etchells & Baguley Vol I to 1926 Edited by W.H.Shercliff
It has some great maps of who owned areas of land and names lots of locals at various times.
In 1777 Brownley green was known as Bronnlen Green
by 1831 it was known as Brownlow.
The only original part left are the cottages at the top of Woodhouse Lane, near the Civic Centre,
The book is hard to get hold of, and can be expensive to buy, I know my local library doesn't have a copy but the City Library in Manchester does. I do have a copy if you'd like to see any of the maps I could scan and email them to you.
What was the name of your family?
Cancan

A Brownley Green Lass & still am!
