These are the children to Donald & Flora:
1824 David
1826 Catherine
1827 Donald
1836 James, Helen & Margaret (Bapt. same day)
1844 Flora, Simona Geddes M & Lewis (Bapt. same day)
Can't say at present whether these are all from the same couple.
I can only see 1 marriage in Ross & Cromarty for a Donald Jack & Flora & that was in 1821.
Added later:
It looks like they are all from the same family according to the census.
These give the "pelicanised" Baptisms births of 1832 Margaret, 1834 James, 1838 Flora, 1840 Lewis & 1841 Simona.
