Dear Ms. Rudeen,
Thank you for posting your request on History Hub!
The Federal Government does not ordinarily create or maintain birth, death, marriage or divorce records, and as you have already researched the U.S. Census, we suggest that you search for records of Rose Dickover’s first and second marriage in the FamilySearch index for United States Marriages or Nebraska Marriages, 1855-1995. This also may provide you with the date and place of birth for Charles Donnell. Then, you may search the appropriate state office to request his vital records.
Since the city of Omaha kept birth and death records prior to the 1904 statewide registration, We suggest that you contact the Douglas County Health Department to request a search for the birth record of Lester Dickerman. Also, please review the FamilySearch Research wiki for Nebraska Vital Records.
We hope this is helpful. Best of luck with your family research!
