I, too, am a descendant of Louisa Huver and William Huver.
Here is I story I heard while growing up in Mobile, AL.: When Henry Steiner married Louisa in 1848, she had a son named William, who was 11 years old. William married Julia Clements, b. 1839, d. of Anderson Clements and Margaret DeMouy. He used the surname of Huver when he married. Later, in the 1860 census, he and Julia have the surname of Steiner. There is no record of a divorce or change of names by William or Julia. When William died, he had the name Huver and is buried in Magnolia Springs Cemetery in Mobile County as William. Julia buried as Julia Steiner. Yet, they never divorces. Family lore is that Louisa persuaded Henry to adopt William (after he married Julia) so he could inherit some of the Steiner fortune (dairy and grocery). Apparently, Henry and William had a falling out and Henry disinherited William, or William took back his old surname. My great grandmother Julia, daughter of William and Julia, retained the Steiner surname when she married Aloysius Brantley Easley. I am also trying to trace the origins of Louisa Huver and William. I don't think William was born in Georgia as I could not find any Huvers there at the time of his birth, unless the name was change to Hoover, which was common. I found many Huvers in New Jersey and Pennsylvania, which is likely where they came from. How did they endup in Mobile? I don't know.
