.rtf is rich text files and some cannot read them. I use Personal Ancestry File as my base program and many of the reports are in .rtf. I have sent you a family Group Record on Mulhall, Joseph 1813. I noticed that itwas a file of about November and I may have minor changes even to this file. It gives us a starting point.
I am subscribed to ancestry.com, U.S. I may switch back to World next year. It's a lot more expensive.
