You didn't mention if Judith and Russell were ever married or not, and when their child/children were born.
I did find in the Wisconsin marriage index a Judith A(nne) Morley married in Barron County to 2 persons, Michael A Conoboy in 1980, and Neil Martin Conoboy in 1983. So, maybe you can look at the courthouse in Barron County for any children born to Judith and Russell, and maybe his place of birth will be listed. This Judith was born about 1948, so given the marriage dates here, it may be likely that Judith & Russell's children may have been born before 1980 and possibly in Barron County. The Wisconsin marriage index starts at 1973, so if they were married, maybe they were married before this year, and there is a marriage record also in Barron County?
