Thanks for the reply Chris.
My particular ancestor was Edward Gaskell. The reference of the page in the 1841 census is HO107-579-11 f-37 p-21.
I have located Halliwell Lane on
www.old-maps.co.uk which has a map of Cheetham from 1848 and Falcon Villa is named on it - towards the junction with Cheetham Hill Road on the left hand side as you approach the end of Halliwell Lane. Marshall Place and Halliwell Place are across the road. I don't know what is there today (I live in York and haven't visited Cheetham).
My initial thoughts, from the name Falcon Villa, and from the fact that there were 20+ people listed as living there in the 1841 census, were that Falcon Villa was one establishment (like a workhouse or similar). From the old map, it looks as though Falcon Villa could just be a small row of houses, but it is difficult to tell.
Any information that you, or anyone else, could provide about it would be appreciated as I'd like to have some idea of why Edward might have been staying there as a 15 year old in 1841 when his parents were in Chorley (where Edward was living again in 1851).
