Dodger, I have been researching Widnes land ownership for some decades now and have an extensive collection of deeds, sales notices, and wills etc. Be in no doubt that your Wright ancestors were in West Bank exclusively.
Certainly Mark Wright lived and farmed 65 acres of Croft's House, but before that the land had been included in William Hurst's land holdings.
Part of the deeds (a very small part) includes the following,
1795 - 'land next to the River Mersey - which was purchased by William Wright from Thomas Hawarden of Liverpool which was the customary inheritance of Samuel Denton, then James Naylor, then Thos Parr (deceased) then Rev. John Parr, then John Parr (deceased) who sold to William Wright, who sold to William Hurst.'
The marriage settlement of Willam Hurst's son-in-law in 1852 includes Coal Brow, Salt Meadow and Moorside Farm (which became Gerrard's Fold). These areas, as well as Croft's House can be seen on the Tithe Maps of c.1840.
The Parr's House of the earlier reply was in Ditton parish and not to be mistaken for land in West Bank. The accompanying photo is of Pickering's Pasture.
