Thank you. I will try that.
Since I first posted, I discovered what caused my second problem. I apparently deleted the person that linked us all together.
I have had some success by clicking on the given relationship, and in quite a few cases it has re-calculated and given the correct relationship. Some of this problem seems to have come from duplicate people in the branch, which I seem to have quite a problem with. Looking at the branch has really helped eliminate some of these problems. Some of the information I have downloaded has also caused problems, with, as an example, on person having two sets of parents. I have had to delete about 4 generations from one branch because of this problem. I still have over 5400 people in my tree, so lots of room for error. I will keep plugging away, before I take out another membership to straighten our the last of the problems.
Thanks for your input. I will definetly be trying it.
