This is one of those not-sure-what-it's-worth-but-it's-fun-to-ponder posts. I was searching for a death record online at FamilySearch.org's Record Search and I happened on two death records for the same individual. WACHOWSKI, ADAM 1908-07-16 CHICAGO 06 MO U 00019664 I wasn't surprised. I knew that from 1908-1915 there are two sets of records for Chicago--but I had never really compared certificates from both sets before. I believe the first record, the one with hurried handwriting stamped with numbers and a date, is the original, and the handwritten number in the top right corner is the certificate number--the one you find in the online index--and that's how those records are arranged. I think the second record is a copy of the original probably made at the Cook County Clerk's Office. Notice that it has a different number in the top right corner--a register number--and that's the way those certificates are organized. Things to notice . . .
