Hmmm - seems we have a little dilemma here, don't we.
I am, for the moment, siding with 'londoner' on this one. (No offence Roy)
Have just looked at the Transcribed Marriage Record on the OPC site and it does definitely show that Richard's father was 'Michael Trahair'.
However, this is a transcription only and it is 'possible' that it may be incorrect.
Depending on the handwriting and quality of the materials used from which to transcribe - I can envisage the possibility of 'Michael' and 'Richard' being misenterpreted.
I have not personally seen the original so can only guess at this so I will be keeping an open mind.
However - Richard Trahair was, according to the 1861 Census, born at St Just in Penwith about 1832/3 and he was a light-house keeper based in the Trinity Buildings at Sennen but working on the Longships Lighthouse off Land's End.
As 'londoner' says - we cannot rely on IGI.
However, the only possible Richard who matches the above is baptised at St Just 24th June 1832 as son of Richard and Constance Trahair.
And, without trying all the permutations, I cannot find a Michael Trahair in the Census Records of 1841, 1851 or 1861.
The 1861 Census record is a little confusing.
Richard Trahair is listed as head of house age 28.
Elizabeth is his wife and also 28.
But then we have Matilda Cock, age 23, as his daughter followed by Louisa Cock, age 11, daughter.
Best of all - Charlotte R.V. Cock, age 1, grandaughter.
This is obviously not correct and will be something to do with other men working 'on shift' at the Longships Light.
And now for the 'coup de gras' - (sorry Roy)
1851 Census - St Just in Penwith - Fore Street
Richard Trahair, head, mar., 53, light-keeper at Longships, St Just
Constance do., wife, mar, 56, St Just
Richard do., son, 18, cordwainer, St Just
Constance do., daur, 16, dress maker, St Just
No Michael in sight but we do have Richard senior as a Light-keeper at the Longships with, it seems, his son following on sometime later.
I think we need to have someone take a very close look at that 1860 marriage entry as it certainly appears to be where the problem lies. (No blame at all on the Transcriber.)
Suggest you do a 'Google Search' using the search-term "longships light trahair" and I think you may find some interesting stuff.
It would appear that your Richard Trahair (bn 1832/3) was at the Godrevy Lighthouse (off Gwithian) in 1881 but appears to have been living in retirement at St Just in 1901.

Once again - sorry Roy but I think that there has been an error in transcription here.
(Been there and done that.)
