Hi Elaine;
I have just been doing a little work on the Organ family as well. So far the oldest who I can connect to my family (in Fortune Bay) is David Organ who, based on his death record, was born in 1829 in Harbour Galley(Galais). So far I have not seen any indication of his parents.
Also in the records around the same time are; Eleanor, Sarah, Elizabeth & John – all born around 1830.
The timing would seem right for a connection to your Michael & Sarah/Mary but obviously nothing concrete at this time.
There is also an Elizabeth Organ (possibly her married name) who died at age 80 in 1899 giving a birth date of 1819. The record indicates that she was born & died at Conne River but buried in nearby Ship Cove (St. Alban’s).
Of course there is Samuel Organ who was born in 1814 at Sam Hitches, near Little Bay on Long Island in Hermitage Bay & who died & was buried at Ship Cove in 1893.
Good Luck.
Cliff
