Yeah, it seems quirky to view them all but not report them all. But for us being able to view them all is just for us, the researcher, to easier keep track without even more "blinking around".
Most other software will not show you all the children of multiple marriages without first clicking to the pertaining spouse. That is so annoying. For a man to have 3-4 wives over time, and 2 of those have 2-3 husbands... to not see all the children with all the half/numbers drives me crazy with the other software... I'm used to Legacy and I'll have panick attacks thinking I lost some kids until I remember...
I've got where some spouses, their previous marriages would be to someone on my side (or that previous spouse had a previous spouse on my side) and the main person I'm viewing is on my husband's side. He too had multiple marriages. Without all the children showing, I can't remember which direction to go and end up pulling up each marriage one at a time looking for what I know is there.
Legacy helps me get it figured out quicker and get to who I was looking for, but couldn't remember the name... the other software that won't show the extra children... is so annoying not doing the same.
All software, the family group sheets though, all report only on the family to the marriage that you are viewing. THAT group's record. Which is what it is, titled correctly. "Group". His other marriages/spouses that you don't see is not part of the 'group'. I reckon this is why other software does not also show half/children because of the 'group' thing. One group at a time. Thus the report of "one group at a time" makes more sense.
