Hi,
I have found a death for John Cochrane 1844 Edinburgh, he died of Inflamation of the Kidneys age 34. This is not uncommon as there would have been dust from the marble they worked with. Annie Grant was born Agnes, this also was common for Agnes to be called Annie, I haven't found a death for her yet. They were married 12/5/1827 North Leith Edinburgh Midlothian Scotland.
I am researching this for a Cochrane that lives in Buxton, Queensland, I wonder if we are researching for people in the same family? Have you uploaded your tree to Ancestry as a public tree? I have a membership at present so I would be able to look and we could compare what we have so far. The amercian Cochrane's went to Ohio and some were Marble cutters there I will send you some details later as there is quite a bit. There is a public tree on Ancestry for Robert Cochrane b 1829 but they have a different wife for John, I contacted them but they said ther's was correct but I'm not so sure. If it is the correct Robert he then went to NZ. The plot thickens!!
More Later
