My 2x great grandmother Janet Milne Longmuir died of typhoid fever in 1855. Last year when I was searching for my families places of burial I found out that her lair had been sold to someone out of the family in 1882. Her husband had remarried in 1876 and all of her children had grown up and moved out of the area.
On the other side of the family, the Munros have a lair in Nellfield Cemetery with four of them buried in it--two adults and two children. The children were ages 10 and 15. Two of the remaining children including my grandmother are here in the US. One is around London somewhere and the others apparently found their own final resting places in Aberdeen.
You're lucky to have found any sort of records. Without a gravestone, it can be very difficult to relatives sometimes!
