Apologies if this has been mooted before,but the following records look interesting if they can be pulled together with a birth for the Rose Peck concerned :-
Death of James Rourke,Doncaster,1927-2005
Death of Rose Rourke,Doncaster,1926-1999 (Rose would be unmarried approx.20 in 1946)
Marriage of James Rourke and Rose Peck Don Valley,4Q 1951
and then from the other end,
Family of Pecks at Farm House,Cantley,Doncaster in 1901 RG13/4415/86/11
Following through generations of the Charles Peck through 1911 and 1939 you will find that Rose is a family name and further components of the address are Top Hall Farm,Bawtry(?) Road(postcode DN4 7BU).This address is just over 2 miles from Doncaster Raceourse(DN2 6BB).
