I have an old FDL Genealogical Society newsletter that lists "index to birth - book 1". I am confused by the column - with no heading - that comes after the "Vol or Year" column. It lists either a "P" or a "F" in the column. What does this mean? Also, I want a brith record for: BURKE, Nellie b. 186-0 Oct. 1, "F", File No. or Page 2338 Are these available from WI State or FDL County?
