I forgot to say, one source citation for a Pension File of one number [my file from 1983]. I have my original request sheet to NARA and had a number on it for the file. I found on fold3.com, one of the title sheets. Includes two certificate numbers. The pension still has one number for all the files included in the Pension record, no matter, what type they are. Letters, affidata or Pay stubs.... Less confusing to find again if you use the record number and not split up the file. Nettie's Genbits Annette DeCourcy Towler
