Going backwards is easier in as much that generally the census is a good guide to place and date, coming forwards is more difficult as the dates/places are unknown and ca be the least likely looking results. Post 1974 council/reg district boundary changes may also have a bearing. I always seem to find that coming forwards with female names results in dozens of marriage options and little to hint at the correct one.
One thing to consider is your parents marriage certificate, there is a possibility a sibling was a witness and you may pick up a married name for a female, it's a calculated risk but at least you should be able to locate that cert correctly fairly easily.
Assuming the births are England/Wales there is also Scotland to consider for later events such as marriage or death.
I will be a nightmare to trace years from now, a dopted aged 1 year there are no pulic documents to show my name change, a marriage in 1989 and child in 1993. As far as the index displays I never married but the name change after adoption is the reason, few if any will know my birth name and will trawl for my birth under the wrong name
