Hi there - there wasn't a census in 1932, do you mean maybe a electoral register or other record?
Looking at freebmd the most likely marriage would be the 1936 to Harold E Turner, followed by a death in 1964 (as Winifred M Turner - age does seem approx correct). All these events are in Luton district.
He may have previously married to Lilian V Young (she died maybe 1932), in which case there were children to this marriage (I cannot see children for the Turner/Bird marriage).
Unless someone can confirm from another source, the marriage certificate might be the only evidence to show if this is the right Winifred.
