Harriett Benson Baptism Date: 9 Aug 1822 Father's Name: John Benson Mother's name: Mary Lankshire
Parish or Poor Law Union: Westminster St Margaret Bishop's Transcript

 

I can only assume that this Harriet is the one who goes to Tasmania to marry Horatio Mason and to be with Dr John and Mary.
see 1800  Mary LANKSHEAR marriage  John MARGETTS and Mason and Margetts - Dr John and Mary Lankshear

I think its clearly Harriet Mason (Lankshear) so the question is who is John Benson.
1823 HARRIET LANKSHEAR in Tasmania marriage to HORATIO WILLIAM MASON 

Perhaps a fellow student of John Margetts? But it is great that John Margetts accepts Harriet and initially in Tasmania Harriett calls him Uncle but later he becomes father.
Did John return all the way to London to bring Harriett to Tasmania? If so perhaps he arranged the baptism. Harriett would have left England soon after the baptism. The father is shown as John and a Doctor - could the Benson be a misunderstanding of course Mary married Dr Margetts in December 1800 and Harriett born in February 1800. hmmmm 

Looking for John Benson an 1805 directory in trades list a Joseph who is in medicine albeit a surgeon

Of course perhaps the J above is for John but what the Sun means in Devereux Court I know not.
There were coffee houses there which became legal Chambers and a pub George's

This is a list of Benson's from the private address section of the 1805 directory
