Son of Henry German and Rachel German (both born in Germany).

He married Rebecca Garrison on 19 August 1824 in Clinton Co, OH.

He died age 72 years 10 months and 19 days.

The cemetery book says he died APRIL 8, 1872 but this looks like SEP to me.

Their children were Mary "Polly" German[married William Webber], Rachel Emma German[married William H. Kelly], Henry German[married Polly Ann Miller], Elizabeth "Betsy" "Becky" German[married Lemuel E. Camp], Andrew German[married Elizabeth "Patience" Betson/Batson], Nicholas G. German[married Sarah Ann Webber] , John German[married Abigail Asbury], George Washington German[married Sarah Jane Dillon], Napoleon B. German[married Ellen Quinn], Lemiel Ervin German[married Isabelle Elizabeth Quinn] and Nancy Jane German[married Irving G. Camp].

Rebecca and Nicholas German, Sr. are buried beside their son Nicholas G. German[and wife Sarah Ann] and three of their children.

Their sons George Washington German and wife Sarah Jane Dillon and John German and wife Abigail Asbury are buried Rose Hill Cemetery, Mt. Ayr, IA. 

Daughter-in-laws Ellen Quinn German and Isabelle Quinn German are buried at Oliver Cemetery, Ellston, Ringgold Co, IA.
