I had to move some cobwebs around in my head, but I do remember seeing a very old-looking tuning fork somewhere along the line among old family papers and belongings. No doubt it will resurface again some day, and when it does I will now know what its significance is thanks to a recently discovered note left behind by my grandmother, Zillah Trewin: Tuning fork used by Grandpa Trewin [Thomas Trewin, 1817-1875] when he led the singing at the chapel in England.
Born on 12 August 1817 to Thomas Trewin and Sarah Larcom, Thomas was christened at the Wesleyan Methodist Church on William Street in Woolwich, Co. Kent, England. According to the Londonburials website, that chapel is now part of a Gurdwara (a Sikh temple).
Whether or not Thomas grew up in and then led the choir in the William Street chapel, I do not know. But I found it very interesting to discover that Thomas had such musical ability and devoted himself to leading choir activities at his church.
As always, comments, corrections, & additions are welcome.
