PS: Ken, if you go to https://familysearch.org/
There is a free search tool where you can plug in names, estimated birth range, location etc to find and trace these families.
There is census data from 1910 to 1940 with Delina/Lina and all there children. You can then plug in the childrens names, birth year ranges etc to find out more.
On a previous answer I incorrectly listed 'Mahoney" as the OH county - because the record was difficult to read. It appears that would actually be "Mahoning, OH"
Often there is an 'image' available on that site that you can save/print/download - for your personal records. Another example is below, showing them in PA
Good Luck with your searches.
