Hi CaroleW,
Saw the Plymouth birth but did not think his mother (nee *) would still be alive. Did not see the sister, but have since found one (*), but the mother is listed as nee *.
Thee are at least 3 marriages in the time frame involved 1960-1970 'ish.(J*)
However I think this will only be solved if some one with Henry in their tree sees this post.
