Geoff and Tricia,
two things:
somewhere you posted a marriage re John Wishlade Hooton (1845?) and Trisha thought that it was too early for Mary's son.
However 1841 Edward and Mary Hooton have a 15 yr old John.
re Selena Hooten (IGI) - looked at 1880 USA for a Selena born 1831 England living in Michigan- would you believe the 2nd one is in the same place as the cemetery mentioned in IGI

Selena Kerman.
Free BMD marriage 1852 Selen Hooten and John Kerman

Now just how that helps or influences this ...
