From what I've been told (and I'll be able to tell you first hand in August when I get the program myself) Family Tree Maker does allow you have same sex couples.
I really feel that them saying it's "too difficult" is their way of saying they don't approve. Ancestry.com allows you do it (as I have done it) so FTM shouldn't be a problem since it's by the same people.
The program I am currently using, Family Historian, doesn't allow same sex couples either. You can put them down as "acquaintances" but that isn't enough. And I can't put both partners down as the parents of their children together, which bothers me to no end.
Anyhow, FTM is the way to go if you want to be able to do same sex couples, especially with children.
Hope this helps!

Any time .. I've never actually used Legacy before but I have been checking it out. I just may download a version to see if I like it. Ideally, I'd like to buy a bunch of used programs, just to get the best of all the different programs out there for genealogy. Hopefully Legacy will work out. I've been hearing excellent things!

Was the information yesterday on Isaacs helpful at all? I hope it will lead you down the right trails.....

It looks like Julius is still in NY in 1870 census

I do see several Abraham / Abram Isaac(s) listed for NY, guess that's a common name.

I'm so sorry, I saw Abraham & Frances and assumed they were yours and just looked at the image but it says he was born Germany, I guess that doesn't match your info huh? Still hunting......
