Dear Jenny H
The children of Thomas Ross, born 1773 to 1832 and his wife Ann born 1769 to 1849 were:
Alexander born 1808 to 1898
Robert born 1811 to 1892
James born 1813 to 1891
John born 1818 to 1910
A possible fifth son was Andrew, but I am still looking for further information on him.
I hope this is of some help.
