I am not exactly sure what the problem is here and I certainly have no idea to which 'other thread' you refer when you say 'see other thread'.
Perhaps I begin to see the light!!
I have checked my database and see that when I added this family back in 2012 I appear to have been unable to identify a baptism record for Frances Tremellin. But a couple of minutes looking at the problem again now and I believe I have solved that part of the problem!!
The marriage record shows that Richard Hocking of Breage married FRANCES TREMELLIN at Sithney 2nd May 1828. The record also shows that neither Richard nor Frances were able to sign their own name but there is nothing to suggest any obvious error. Richard and Frances even named a daughter 'Frances Tremellin Hocking' in 1841 (even though the baptism record shows the surname as 'Hollow'!!). (The GRO Birth Index confirms the name as 'Hockin')
Census records and the burial record for Frances suggest she was born at Phillack sometime around 1806 so I tried search for Frances in the OPC database using wildcards as follows - F TR%M%L%N. This produced no possibilities so I searched again to see what might be found based on your thread title. From that search I have found a 'potential' solution to the problem.
The Phillack Parish Register shows the following baptism:-
23rd November 1807 Francis Tremelling the son of Wm. Blewett and Elizth. his wife was baptisedI suspect this might be a not uncommon error by the Vicar and that this might actually be ..... Frances Tremelling 'daughter' of .....
And I believe the father of this child (William Blewett) was the son of William Blewett and Frances Tremelling who married at Phillack in 1777.
Further confusing matters now is the fact that I cannot find a marriage for a William Blewett (var.) to anyone named Elizabeth who could be possible parents of Frances/Francis Tremelling Blewett.
So I wonder if this might be another clerical error.
The nearest possible marriage appears to be that of William Blewett and Loveday Barnicoat at Phillack in 1803. However Loveday Barnicoat was baptised at Phillack in 1756 so would have been 47 at marriage and she was buried at Phillack in 1834 at the age of 78. I have not identified this William Blewett but he and Loveday had no children.
AHA! - a correction to my last statement. I have indeed now just identified William Blewett and the identification might now help with the links to Frances Tremelling Blewett. Looking at the marriage records of William Blewett to Frances Tremelling and then William Blewett to Loveday Barnicoat shows that William Blewett was one and the same man!! He could not sign his own name but used a unique sign to make his mark. That was a 'W' made up of two Vs overlapping.
William and his first wife Frances had four children - William (1777), John (1780), Mary (1783) and Jane (1788) and I believe it is William (1777) who was the father of Frances Tremelling Blewett. Problem is I cannot find a marriage for him.
Neverthless, William (and mystery bride Elizabeth) had six children baptised at Phillack from 1803-1816 and William himself died and was buried at Phillack in 1816. I have not yet been able to determine what happened to William's wife.

The second part of your query was about the parents of Richard Hocking. I don't know where the idea of Sampson Hocking might have come from but if you look at the children of Richard and Frances it is difficult to accept the possibility of Sampson being the father of Richard.
Richard and Frances had 10 children that I am aware of and of those there were five sons - Edwin, Richard, William Edmund and John. The fact there is no Sampson is generally a good indicator to suggest there was no-one of that name in the close family of Richard Hocking.
The 1851 Census gives Richard Hocking's birthplace as Grade which is on the Lizard Peninsula and just down the coast from St Keverne. And his age in 1851 was 49 suggesting he was born about 1801 or 1802. There are just two baptisms anywhere around The Lizard for a Richard Hocking (var.) within a few years of 1800:-
Richard son of John and Jane Hocken bp. 27th October 1799 at Landewednack
Richard son of Edmond and Mary Hockin bp. 6th February 1803 at St Keverne
I would suggest your Richard was the son of Edmond and Mary.
