Hello Mike, Having seen the answers to your query my suggestion is that you enter the length of a marriage in the personal notes for the persons concerned. That way you will have the information at hand. I do that sort of thing with recorded death ages and abode of parents at christenings of their children etc. Regards, Rod in Andover. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com
