Thomas Wallin and Nancy H. Pollock are my gg-grandparents. Their son James Bowden Wallin b. 9/24/1849 d. Feb. 1902, married Susan (Sudie) Thomas b.12/7/1873 on June 22, 1892. There was a 24 year difference in their age. They had 4 children before James Bowden Wallin passed away with pneumonia.
I have been able to get quite a bit of information on the Hastings, Pollocks, etc., but finding Thomas Wallin's correct family has been quite a challenge. YDNA has him linked to Elisha Wallin the Longhunter.
