Margaret Rebecca Boyce is on Geni as being born 1799 Parramatta - the daughter of Captain John Shortland, Jnr, RN [Marine "Sirius" "Friendship" 1788 + Marine "Reliance" 1795] (born 1769) and Elizabeth Shortland
Everything that I have found on John SHORTLAND born 1769 says that he did not marry
I have looked at My.Heritage trees and some have her father as Commander John Shortland, Snr, RN [Crew "Supply" 1788] (born 1736).
Margaret also has a brother John Thomas Shortland (born 1796 in England) - John had returned to Australia in 1795 on Reliance
Can anyone add any supporting documentation on Margaret or her brother John
