Hi,

Edgar Albert Hobbs
Born: 14 Jan 1906, New York City, Queens, NY
Father: Charles Hobbs, b. England, 32
Mother: Bertha Shafer Hobbis, b. NJ, 26
Source: New York, New York City Births 1846-1909

There are a couple of Bertha Shaefer's in the 1885 Census for Hudson Co. NJ but I don't know which one is yours.

That's all that I found for her. Successful Searching!
