William Henry Mccormick and Pearl Infinger

I am looking for the parents of William Henry Mccormick born 1893-1895 Walton County, Florida possibly Freeport. He married Perl/Pearl Infinger she was born 1901-1905. They had three children Myrtle born 1937-1938 J. D. possible first name for J.D. is John born 1942 and Fannie born 1945. Henry raised Pearl's three children from her first marriage to Asberry Brown they were B F Brown, B J Brown and Sadie Brown. Pearl died 1954 Walton County, Florida and Henry died 1958 Walton County, Florida. I have found them living in Freeport, Florida in the 1945 Florida Census records. After the death of Henry and Pearl their three children moved to the southern part of Florida. Any help will be appreciated.
