Dear Ms. Rock,
Thank you for posting your request on History Hub!
We suggest that you verify the Dowdle lineage by carefully consulting primary documents such as birth, marriage, and death records. These documents may ensure that the same names and vital dates are maintained for each generation. We also suggest that you contact the appropriate State archives or historical society to request a search for these vital records. In addition, please review the FamilySearch Research wiki for United States Vital Records.
We hope this is helpful. Best of luck with your research!
