I have been poking around in MacFamilyTree. it seems alright, but unless I am missing something (which is possible as I have only spent a short time looking) it lasks good support for multiple marriges, half and step siblings. Of coarse I could have just missed the features or they could be disabled in the locked version.
There is no demo available for Reunion 8 yet, but thanks for letting me know about it. I thought they went out of business or something as I haven't seen any of their new versions since about 4 or 5.
Thanks again and keep the suggestions coming if you have em.
