This is a reply to a rather old post, so you may already have the info.

Infant Grace Genice Proctor b. Aug 04, 1924 d. Feb 22, 1925 Tampa, FL
Buried: Jackson Heights Cemetery, Tampa, Hillsborough, Florida, USA

Parents:
William Murchinson and Josephine Kemp Proctor

William's Parents:
Colon Murchinson and Mary Ann (Sykes) Proctor

William's sister:
Nellie Florence Proctor wife of Joseph Warren Mason which may or may not be the Nellie you are looking for.

Several of the above Proctor's are buried at Myrtle Hill Cemetery in Tampa, but I do not reflect Grace being buried there per your obituary reference.

Hope this helps, if you do not already have.
