Hambrick - Sheridan connection

While working on the 1930 Banks County census today, I ran across the following:
1930 US Census Banks Co GA Anderson GMD Saville & Burns Road HH 140 144:
Hambrick, William H. head m w 70 wd 21 GA GA GA farmer
Hambrick, Rosa A. dau f w 35 s GA GA GA farm laborer
Sheridan, Ellen M. dau f w 27 m 27 GA GA GA farm laborer
Sheridan, Samuel son in law m w 26 or 20 m 26 or 20 GA GA GA farm laborer
Hambrick, Margaret gr.dau f w 8 s GA GA GA
Hambrick, Otha T? nephew m w 5 s GA GA GA

This caught my attention because there are Hambricks buried at Grove Level and Silver Shoals and I knew Sheridans were also in the Maysville area.  I can somewhat remember Sam Sheridan (listed above) living in Maysville on Wilson Street not too far from Perino Boswell and directly behind Bobby Crane's house on North Main.  The Sheridans had a simple place not much improved.

I noticed on the above census entry that Sam Sheridan and Ellen Hambrick were newly married in 1930, and living with Ellen's widowed father.  Interestingly, I had ran across Ellen Hambrick's name when transcribing Georgia death certificates for Maysville from the 1920's.  I didn't know who she was at the time, but noted that her infant son died in 1923 and no father was listed on the death certificate, indicating she did not marry the father.  I now believe she had two children while unmarried before marrying Sam Sheridan.  The Margaret Hambrick, age 8, above, is likely her child as well.  I cannot figure out who the father is of Otha T. Hambrick, age 5, listed as a nephew of William H. Hambrick.  I have been unable to verify William Hambrick having a brother, so Otha may have been the child of one of his unmarried daughters.

I would love to correspond with any Hambrick or Sheridan researchers!
