The pictures having an HL designation are from H.L.'s album. The ones designated as MHL and MHLG are from a box of photos belonging to H.L. Next to both the HL24b and HL23 photographs in the album is written the word, "Daddy." Also, next to the HL24a photograph of Henry L Cook Sr. was written the words, "Grandpa Cook." It is due to these identifications that Fred is identified as the older brother of H.L. in HL23.

It should be noted that there was 7 years difference between the ages of Fred and H.L., and the age difference of the two people in the photograph appear to be considerably less than 7 years. But some people appear older than they are and others appear younger, and an age difference of 7 years is not impossible. The identification of H.L. is undoubtedly accurate, and this would certainly appear to be a photograph of two brothers.

Also, once HL23 and HL24b are established as H.L., the identification of H.L. in MHLG1 is easy.
