I've been searching the IGI for missing ordinance dates on some of my family and have noticed an entry I don't understand. It is the entry "prior to1970" and is also sometimes written as <1970>. It seems to be used in lieu of the actual date. I guess my question is what happened in 1970 that was so important that it was granted an exception to the rules of entering dates? I searched carefully in the text book I used to learn genealogy from, but it was printed in the 50's and would be unlikely to have anything about the 1970's in it. Can anyone help? -- Byron O.
