My grandfather, Frederick G. Knowles, is listed as an adopted son on the 1900 and 1910 census for Tarpon Springs. His parents are listed as Edwin T. Knowles and Eliza Meadows Adderley, both originally from the Bahamas. Family legend has it that Frederick was the biological son of Edwin and Eliza's sister. Does anyone have any idea how I can find any record of adoption or of biological parents? Would the papers have carried a birth announcement? Frederick's birth date is 1 May 1893 in Tarpon.
