Hi Wattsy
               The marriage licence is normally a document that contains the details of the marriage, place, date, bride, groom and witnesses (not nessaraly parents) the church would be St Edwards and the records are kept at Staffs record office. You can find details of how to obtain a copy on this link, you may have to pay.
http://www.staffordshire.gov.uk/portal/page?_pageid=47,70360&_dad=portal&_schema=PORTALWhile I remember I had a email chat with a Macclesfield friend who has done a lot of reseach into pubs and breweries in Macclesfield and he sent me all the info he has relating to the Dawsons in the licence trade in Macclesfield,much of it just confirms what is known already plus some extras. details below
Checking my records for the White Bear, King Edward St. - I have the following licensees listed (mainly from trade directories) 
1818        Joseph Shaw
1822-3     E Dawson (London Directory)
1824        Elizabeth Dawson     (Piggot & Dean)
1825        ditto
1828-30    ditto                        (Piggot)
1838        James Dawson        (I have a mention of James in 1831 also)
1841        ditto
1844        ditto                        (Slaters)
1846        ditto                        (Williams)
1848        ditto                        (Slaters)
1850        Edw. Dawson             
As for the Lamb, Stanley Street. - I have the following relating to the Dawson family:- 
1818        Thomas Dawson        (Piggot)
1822-3      James Dawson
1828-30    ditto                        (Piggot)  
In Pigot's 1838 Directory there are 3 Dawsons listed:- 
Mrs Elizabeth Dawson        Great King Street
James Dawson, vict, White Bear, King Edward Street
John Dawson, vict, Struggler, Watercotes 
The first two are also listed in a Piggot directory for 1841 
In Slater's Liverpool Directory we have;- 
Dawson Mrs Betty, Great King St.
Dawson James, vict. White Bear, King Edward S.
Dawson John, shopkeeper, Park Green 
By 1857 the only directory entry (relating to the licenced trade)  is for a John Dawson (beer retailer - Steeple Street. Possibly the Franklin). He is still there in 1860. 
By 1864 no Dawsons associated with the trade.
