Very helpful thoughts. I have deleted my sister and her family from the ancestry files.
I purchased family tree maker the other day and am going to change it so it is not linked to ancestry. I know I will have to manually update it but maybe since it is not online but maintained on my computer the information will be more secure and I can make "family trees" for the family members who are interested. Family dynamics are so interesting. With the help of one of my nieces, I am putting together a good collection of family pictures and may make each of the nieces and nephews a memory quilt with pictures and embroidered names and dates.
Thanks again for your advice. I really appreciate it since I have just started this research.
