In computer language I would use * Jones between 1936 & 1950 but this doesn't work.
That process - without the * in the first name box, leave it blank - is effectively how you enter the details (married surname, mother's maiden name, area, date range) on freeBMD as suggested by heywood. The same applies in FindMyPast. Unfortunately you are likely to get a lot of births if the surnames are common. The 1939 register may show up the first child (if he / she has now died so is not redacted).
Bear in mind that any children born to that couple may still be alive so cannot be named on here.
