I sowed confusion here -- it was the son of Elizabeth Hawkins and John Colwill, Charles Colwill, who emigrated to Australia pre-1841 with his wife Eliza Lemon (the Lemon thread).
Information about Charles Colwill and Eliza Lemon is taken from their records in Australia, and that's how the name of Charles Colwill's mother Elizabeth Hawkins is known, I think.
And/or woolara found the marriage of John Colwill and Elizabeth Hawkins in 1812 in Kilkhampton.
So as I said -- What you are actually looking for is the family (parents ...) of Elizabeth Hawkins who married John Colwell in 1812 in Kilkhampton?
I think this thread is a good example of how it's best to ask the question one really wants answers to, rather than tangential questions about people who may or may not be related.
The subject of interest here is really Elizabeth Hawkins who married Charles Colwill, and the various senior Hawkins chaps in the vicinity are just people who may or may not be related to her (e.g. brothers).
I certainly think that identifying siblings can help find more info about one's person of interest, for instance if a sibling's birth/baptism record can be found even if a record for the person of interest can't.
But for others to help, we do need to know what we're looking for, to start with.
