Hello again Kathleen, continuing with John of Grenada. Family records show he had 8 children: Alexander (b 1808), Helen Jane, Georgina, Margaret Udny, Jane Augusta, Hannah Carnegie (bt 1816), Mary and John (b 1822-3). His will shows that Alex, Georg, Jane and Hannah had died before 1824. John (b 1822) married Flora Anne McKinnon in Calcutta in 1856, and had John K.M., Helen, Alex and Jessie in India, and Charles and Robert on their return to Aberdeen in about 1816. They can be found on the 1871 ans 1881Census in Old Machar, Aberdeen. Good Hunting!
