There's reason to believe this name is completely wrong:
The 1910 census records "Helina Lambert" as Celia's daughter-in-law along with George (her son) and Elaine (her granddaughter). The obvious assumption is that George married Helina prior to April of 1910 (unsubstantiated marriage date is April 21, 1909) and had a daughter with him named Elaine (unsubtantiated birth date is February 3, 1910.)
"Helena Bertha Lambert" does not exist in the 1900 census records as part of Alfred and Virginia Adams' family. Their daughter Eleanora is listed as born in 1885 on the 1900 census, but does not appear on the 1910. Another daughter, Orora, is listed on the 1910 census, but with a birth year of 1892. So, although "Orora" could have been a faulty rendition of "Eleanora" by the census taker, Eleanora would have been 25 years old, not 18.
There is also a Lena B. Adams - Father Alfred, Mother Eliza - from Oneida, NY with a birth year of 1878. Theoretically, her full name could be Helena Bertha Adams, but she would be 7 years older than George Napoleon Lambert, which would have been unconventional for a marriage at the time. (Not to say impossible.) If that's great-great-grandma, then that whole branch of the tree is wrong.
