I found William Heddy's death notice in the vital records-it listed cause of death as old age, date of death 12/11/1903, age 83, resided at 2018 McLemore in Memphis and had been a resident of the city for 8 years. He was married, His birthplace was listed as Pennsylvania and his mothers maiden name as Ayers.
The lat. and long for his Tippah County location mentioned above is 34'52'01 N and 88'54'16 W. in southern Tippah county
On the goggle earth satelite photos there appears to be only a few residences left in that section. Next time I'm at the library I'll see if I can find an Obituary for him.
