Rebecca fowkes baldwin green

I am looking for further information on Rebecca fowkes (1813-1896)family. Her father was probably John Frederick or Ferdinand fowkes. Unknown mother. First marriage was to a John baldwin mar 1837 macroom. He died in 1839 of scarletina in ballyvourney. Was he from either of the baldwin families?  Second marriage registered in rathclaren but maybe done in Brandon to William green, son of Daniel green farmer most likely destserges 1803. Death maybe 1857 San Francisco, ca.
