I can help you with the Hungerford side back to the first Thomas Hungerford.Elbert's parents were John & Nancy (Callahan) Hungerford.I have more if interested.
I have access to a website that allows for census searches.I did a quick search--not all-inclusive by any means--but I did find a Sarah Crull in Indiana in 1870.She is the daughter of "Hesekiah" and Eliza Crull.The family can be found on pages 21 (also listed as page 45)and 22 of Miami county, Clay township, Waupecong Post Office. They lived on real estate valued at 65,000!Hesekiah is listed as a farmer, age 42, born IN.Eliza, age 42, born OH.Children: Catharine, age 17, born IN; Mary, age 11, born IN; Martha, age 8, born IN; John, age 7, born IN; Margarett, age 5, born IN; Sarah, age 2, born IN; Teena M. (I think), age 8 months, born in September of 1869 in IN.Also living with them is John Cling, age 26, born in Ohio--no job or relationship listed.
I looked at all the families of men 17 to 49 years of age and found only one Sarah.If there is another Sarah (or more), she/they are living with females only or elderly men.
If you want more about the Hungerfords--let me know.I hope this helps.
