"The Nihiser Family, Then and Now"

I am researching the NIHISER family.
I was born August 7, 1948, in Van Wert, Ohio, the daughter of the late Lawrence Alvin NIHISER, who was born on July 11,1909, and Erma Mildred (FACKLER) NIHISER. Both my parents were born in Van Wert Co., OH. Lawrence was the son of John Price NIHISER, who was born April 13,1875,in Allen Co., OH and Mary Elizabeth(KOHN) NIHISER, who was born March 29, 1883, in Van Wert Co., OH.
John was the son of Milton NIHISER, who was born in Fairfield Co., OH on April 2, 1853, and Mary Magdaline(STEMEN)NIHISER,who was born in Van Wert Co., OH in 1850. Milton was the son of Amos NIHISER, who was born circa 1826 in Hocking Co., OH and Rachel (SIGMAN)(SIGMON)NIHISER, who was born circa 1828. Amos remarried in 1869 Mary(POVERMIRE)NIHISER, in Allen Co., OH.

Specifically, I am trying to locate Amos's parents, deathdate, and the deathdates of his two wives. I am also looking for the NIHISER immigrant who came to United States.

I am seeking information on Amos's family line, but I would like to hear from and share information with anyone else interested in or connected to the Nihiser family.

I am looking forward to sharing the puzzle with you.
