I have been searching for sometime for Joseph and Susan Cook Wallin, and today at the LDS Site I found them! Married Nov 19, 1833 in Keyham, Leichester, England.
I know that one son is John T. Wallin(g) born July 3, 1840, either in England or Kings Co. NY. Looks like from the LDS site there is a brother Richard Wallin, christened 30 July 1834 at St.George, Leichester, England, with parents listed as Joseph Wallin, and Susan.
I can not find them in the USA. In John T.'s obit is says he came to Brocklyn with his family in his youth. But I have not found them yet. But its just today, that confirms that his parents were Wallin, not Walling.
If you have any information on this family, would love to hear from you. Thank you, donna and richard walling firstname.lastname@example.org
