Check a family tree for errors
Drop the .ged and open “Fix”: problems are listed first, then things worth a second look. Click a line to go to that person.
What is checked
Death before birth, burial before death, marriage after death; a mother younger than 12 or older than 55 at a birth, a father younger than 13 or older than 80; a child born after the mother died or more than a year after the father died; very long lives; links to people who are not in the file; people who appear among their own ancestors; families with nobody in them.
Dates
Dates written as “12.03.1890”, “March 3, 1890” or “abt. 1890” are read correctly here, but some programs do not read them. One button rewrites all of them in the standard GEDCOM form; dates that cannot be completed, like a day and month without a year, are listed for you to fix by hand.
