Not quite; there was a female Standeven/Robinson born (1933), who is probably his sister, but the marriage in 1960 could be for another Standeven female (with a similar set of initials), who was born in 1935 in Croydon, which is more likely for a Surrey marriage but without certificates it is impossible to prove.....or disprove.
These could be his parents:
Leslie Standeven SeptQ 1925 Halifax 9a 1135 Bride: Dorothy Robinson
these could also be the parents of the child born in 1933 in Halifax.
