Hi, my Hugh Pill had a very large family - so there are quite a few of them around - I have found on the 1841 census that the other coastguards listed at Sennen Cove were Charles Poynter 40 Navy Half Pay, William Mean 30 Coastguard, Richard Forward 35 Coastguard, Anthony Spiller 35 Coastguard and William Moyle 55 Coastguard - they all lived in the Coastguard cottages in Sennen - there are quite a few coastguard sites that list the men so maybe you might have a bit better luck there. (e.g www. morrab.tripod.com) let me know how you get on and I will see if I can find anything out for you also.
