Robert Gibson Died Before 1841 MD Margaret Bicket 1778

Hello,

I have been researching my GIBSON side of my family tree,
Scotland, + Australia,
and now i am back to Robert GIBSON, he died befor 1841,
he married margaret BICKET, ( b; 1778). - Scotland.

their son john ( 1827 ) ,was my great great grandfather,
( he came to Australia.)

im hoping someone might know who robert GIBSON's parents were, etc,
or margaret BICKETS parents ??

any info appreciated,
