Hi. I always make volunteer research available not only to the person with the query but also to anyone seeking this family history. Thus I am posting rather than emailing. Hope that's okay.
The 1940 US census is now fully indexed and free to search at Ancestry.com.
I'm not sure exactly what you are seeking?
1940 Oakland, Alameda, California Address: 2632 Valdez Milton C Headding 37 b abt 1903 Missouri, installer, screen windows Gladys N Headding 37 b abt 1903 Nebraska Robert Lebdell 16 stepson b abt 1924 Wyoming Betty Lebdell 13 stepdaughter b abt 1927 Wyoming Milo G Headding 3 son b abt 1937 California Residence in 1935: Same Place (a question on the 1940 census)
I’m showing the “Lebdell” name as transcribed; the original handwriting looks like Lobdell.
As for Charles Dudley Lobdell, there’s more than one Charles Lobdell, so please add an approximate birth year and birth place. I can’t tell if he’s a husband or contemporary of Gladys, or a son of hers. In a simple search (with no DOB) I could not discern him.
Ditto for Edson Gering. Is he Gladys’s father? Born about 1862? And her mother is Nellie Winner? One son of this couple is listed as born in Scotts Bluff, Nebraska, which makes me think it might be the right family. http://records.ancestry.com/Gladys_Gering_records.ashx?pid=24634811http://records.ancestry.com/Gladys_Gering_records.ashx?pid=24634811
Please post a transcription of the 1930 census for both Edson Gering and Charles Dudley Lobdell, since you have that record. Thanks. Perhaps you'll search the 1940 census yourself and can add those if you find them.
I find a WWI draft registration for a Charles Dudley Lobdell born 21 April 1884 in Nance County, Nebraska.
