January 26, 2013 note from Bonnie Walser (firstname.lastname@example.org), "...Iredell County Register of Deeds has this grave listed as JN Infant Son Robbins.
Probably infant of John Newell Robbins & Caroline N. Hinson.
Unsure of this, as Caroline's 1900 census has her having 7 children / 6 living which have all been identified. We do know this is not the same baby as Linnie May because her stone is readable and this baby's is almost totally blurred (although the dates look to be 1900). The stone photos were taken on the same day and although hard to make out, the stones look to have similar markings.
Possibly this baby was born and died after the 1900 census taker was around.
