Presumably, the lack of an automatic process for identifying twins is down to the uncertainty in the question. Obviously, twins don't have to be born on the same day, they could for example be born either side of midnight. But there may be more to it - could twins be born more than 24 hours apart, if so how far apart? Does anyone know? Would it be good enough to look for multiple births from the same parents within a given timespan, say a month? Then you have to deal with incorrectly entered data resulting in false twin flagging. Also, you have to cancel the flags if dates are changed, persons moved to different parents etc.
It's not impossible, but the process gets a bit complicated.

I'd say it would be quite easy to do if the programmers wanted to incorporate such functionality in the program. Yes, a simple search based on births from the same parent within a specified period, say one month, would be adequate. If you could vary the period, all the better. The issue of incorrectly flagged data is of course something you have to deal with with any operation you perform so I don't think that's really a problem specific to identifying multiple births. Now I'm wondering if there is any program that enables easy identification of multiple births?


Do you have a copy of MS Access?

If not, read no further.

If you do, get a free copy of Legacy, make a GEDCOM from FTM and import the data into Legacy.

The file will end up in somewhere like c:\legacy\data, with an .fdb extension. So right click on that file, and open it in Access.

Go to Tables, find tblIR (individual records). Make a query to check 2 fields - birthSD and surname - for common duplicates.

You will have to steer around empty birth dates (stored as -99999999) and partial dates - eg, entering 2003 will be stored as 20030701, the 1st of July. But it is an easy way to get very close to a shortened list...
