My name is Brian Snider, h_brian.snider@bmonb.com

 a descendant of William Gooderham's daughter Louisa, who married a Toronto merchant William Walker. Their daughter, Harriet Rodwell Walker married by great grandfather John Elgin Snider. I have attached a link to our Snider family web site for your reference on the family line. I noticed on one of your links to a handwritten family tree that Louisa was associated with the name Score. Though not evident in the Snider site, I do recall a family reference to "Grandma Score" which may have been a second marriage.
