i was fascinated to read about the Sussex being used to take a bride across from Bryher to Tresco. the bridal couple were my grandparents, Reginald Vickery and Bertha Jenkins, they both worked at Tresco Abbey, he was a gardener and she was a maid. they had to marry on Tresco because Bryher church was not licensed for weddings. they went across sat next to each (so much for the bride not being seen by her husband to be), they were married for over 50 years! the timing of the wedding, was dependent on the tides (thus it ever was on Scilly).
