| Function Name: | EstimatedBirthDate | ||||||
| Description: | Uses available information to estimate a person’s date of birth. | ||||||
| Minimum FH Version: | 3.1 | ||||||
| No. of Parameters: | 3 | ||||||
| Return Type: | Date | ||||||
| Parameter 1: | A reference to a record. | ||||||
| Parameter 2: | This parameter can be used to modify the behaviour of the function.
|
||||||
| Parameter 3: | A number. This is an optional parameter. If not
supplied, the value will default to ‘2’. This
parameter affects the number of generations
that will be checked to try to find a date that
could help estimate the person’s birth date.
Family Historian will use any dates it can in a person’s record for preference. If it doesn’t find any, it will normally check parents and children’s dates, and try to calculate birth dates from these. If still no luck, it will normally check grandparents, and grandchildren’s dates. How many generations up or down it will continue to check, if closer generations have no dates to work from, depends on the value set here. If you set this to a high value (e.g. 10) some individuals who previously had no estimated birth date (because nothing to go on), may now have an estimate. The higher the value used, the more results returned you can expect. But the range between the EARLIEST and LATEST values in these cases is likely to be large, and the function may run slower. You can set this value to 0 if you want fewer, more accurate results. |
