I posted this question in an older thread but got no reply, so I'm posting it again. Maybe because it was considered an old post?
Can anyone comment on the accuracy of the Relationship Calculator? When running a calculation in RootsMagic I get six relationships between two people in the family tree, which is not unexpected due to endogamy in this particular family. However, when I run the exact same database through Family Tree Maker's relationship calculator I get one blood relation and three non-blood relations between the same people.
Thanks for any input.
