I think so. I resisted the idea of spending the money for about a year. My wife finally pushed me to do it. I have never regretted it. I have found pictures as far back as my 5th great grandparents that another family member had. I had never seen them before and have been able to share them with the rest of my family. I have come across so many relatives that I had not met or hadn't seen in years. To me the pictures of relatives that I did not have are priceless and would have been lost to me and my family had I not done it.
I have even done the ancestry DNA which has been a really interesting line of discovery for me.
