I have no info on 'your' Col. Wm. Spring, however, my GGGrandfather was a Wm. Spring. My GGrandmother was Catherine Spring Griffin, dth cert indicates..born Cty Kerry. Interesting..the timeframe is off as my Catherine was born about 1845 but the message caught my eye.One of Catherine's children was named Francis (died before 1 yr. old).Is William Spring from your line?
