Hi .... Just found your message from 2001. I don't know if you need additional information on the Aldrich family, but do check out my tree (McKeag/McCracken Family Tree). My grandfather was Lewis Dostal's brother. I do have some information the Aldrich's in the tree, but you may already have this information. Good luck!
Lewis's wife, Lillian, has done extensive research on the family and I'll see her at a family reunion in Iowa this August. She is making a copy of the family history she has. Let me know if you would like any of the information.
