Searching help -
When you have isolated the birth year of the person you want, you can then narrow the search progressively: e.g. 1905 - first search 01/01/1905 to 31/12/1905
2nd search (on the same name of course) 01/01/1905 to 30/06/1905
If nothing there then 3rd search 01/07/1905 to 31/12/1905
If the name still appears, then narrow the search range to the 3rd quarter of the year, then the 4th if necessary
Then to the month
Then to the fortnight
Then to the week
Then to three days/two days/one day.
For legal or official purposes of course the certificate or printout must always be obtained.
