Dear Stephen,
This is what I have managed to find out so far.....
I should say that the handwriting was very poor and very difficult to make out
The Tithebarn at 27 Lord Street PrestonIn the 1891 Census, 27 Lord Street is "The Imperial Hotel"
Residents: Richard Portman (It looks like!)
Head 43 Barman born in Cottam (I think)
Margaret Portman Wife 43 born in Preston
Lilly Banks Portman Dau 23 Cotton Weaver born
In Salford Lancashire
Annie Banks Portman 18 Cotton Weaver born in
Salford Lancashire
George Banks Portman 16 Cotton Weaver born
Salford
John Banks Portman 14 Scholar born in Salford
Nellis (looks like) Banks Portman 9 born in
Manchester.
I checked the Directory for 1855 and both these names were not listed.
It could however have been run as a beer house as there were many on the Lancaster Road in the 1850's
The Golden Cross 60 Lancaster Road Preston
In the 1881 Census, the address is 187 Lancaster Road.
Residents:
Richard FOXTON Head M Male 53 Richmond, York, England Inn Keeper
Jane FOXTON Wife M Female 51 Rochdale, Lancashire, England
Richard R. FOXTON Son Male 14 Haywood, Lancashire, England Scholar
Mary J. WALMSLEY Visitor U Female 17 Rochdale, Lancashire, England Scholar
John BRINDLE Boarder M Male 76 Preston, Lancashire, England Varnish Manfr (M F)
Harriet WATKISS Servant U Female 18 Lawleybank, Shropshire, England Genl Servant
Again this was not listed in the 1855 Directory.
Black A Moor Hotel 175 Lancaster Road Preston

In the Local Directory for 1855 it is listed as the "Black A Moor Head" at the hands of James Smith.
In the 1891 Census the Residents are the Maison or Mason (I think)
James Maison Head 38 Manager of Public House born in Wrexham (I think)
Alice Maison Wife 27 born in Bedford Leigh Lancashire
James son 4 born in Bolton Lancashire
Blake son 2 born in Bolton Lancashire
Maud 10 Months born in Ashton Lancashire
Alice Smethurst Barmaid 29 born Lancaster
Ellen Manning Servant 25 born in Garstang
I shall go and do some more digging around.
If you get chance it is worth you going to the Library on Bow Street. If you ask to see the Local Directories you can check by year to see who was resident at the time and it may help you work out when these Public Houses were built.
It may also be possible to view old Photographs of these buildings at the Library.
