William John Swainson, FRS, FLS - Incorrect name

Hi Tim, I'm researching the life and works of Rev. Charles Swainson, (naturalist), who was the son of Charles Litchfield Swainson of Crick, Northants., who was the half-brother of the above William Swainson. I have discovered quite a lot about Charles (1841 - 1913), and visited his parish recently in Old Charlton (St Luke's) where I was able to enlighten some of the parishioners about their previous Rector! I have a photograph of him which may be the only one in existence, and a photo of the old Rectory, now gone, where he wrote his "Provincial Names and Folklore of British Birds". I have also found where his grave is after years of searching, and am carrying on his research into the origins of bird names [at Glasgow University]. Would you like to correspond? I would love to share my notes with you. Michael McHugh
