Christian Mohr was born in Sulzfeld, Germany on November 22, 1829. Sulzfeld is a small town in the German state of Baden-Württemberg that borders France and Switzerland. Christian was the third oldest of seven children of Friedrich Georg and Dorothea Katharina Mohr. His father owned and operated a small farm in Sulzfeld.

Christian had just reached adulthood when, in 1848, revolution broke out in Germany which drove many German families to America. Christian's father took sides with the people against the government and, in consequence, his property was confiscated and he was reduced to poverty.

Christian and his family immigrated to the United States in the spring of 1849. They sailed from the port of Rotterdam, South Holland on the steamship Louise. The family consisted of Christian's parents, three brothers, and one sister. The brothers were Frederick, Gottlieb and Jacob, and sister Catherine. An older brother, Carl "Charles", had immigrated to America earlier that year. Another sister, Jacobina, died in infancy in 1832.

After arriving in New York City on July 5, 1849, the Mohr's settled in Mansfield in Richland County, Ohio. The following year the family, except for Christian and his older brother Frederick, removed to Van Wert County, Ohio where Friedrich purchased 80 acres of land in Sections 18 and 19 of Hoaglin Township. Christian and Frederick worked to earn some money in Mansfield before following their family's path to Van Wert County the following year.

Arriving in Van Wert County, the two brothers bought land in Washington Township. Christian later sold his interest in the land and soon after bought land in Hoaglin Township. At that time there were just two roads cut through the woods north of Van Wert and the settlers were few and far between.

The territory north of Van Wert was originally called the "Great Wilderness" or "North Woods". The territory extended in unbroken density for a distance of 35 miles and was shunned by the early settlers. Enoch Hoaglin was the first white man to settle in Hoaglin Township. He arrived in the spring of 1839 and erected a log cabin on the south bank of what is now known as Hoaglin Creek in Section 18 of the township. Enoch found the land to be fertile for farming but it was still several years before widespread settlement began. The Mohr's arrived at the start of a period of rapid population grown in Van Wert County. The 1850 Census shows only 268 people living in the county. Within ten years, that number grew to 1615.

Christian married Marianne "Mary Ann" Leist on September 30, 1856 in Hoaglin Township. Christian's older brother, George, had married Mary Ann's older sister, Elizabeth "Lizzie", the year prior. Christian and Mary Ann had 10 children, 4 boys and 6 girls. One girl, Catherine, died at birth. They spent the remainder of their lives on a 160-acre farm in Section 16 of Hoaglin Township. They were of the German Methodist faith and worshipped at the Grand Victory Evangelical (Association) Church that Christian's father helped to establish.

Marianne "Mary Ann" (Leist) Mohr died on February 13, 1891 at the age of 50. Christian Mohr suffered from "stomach trouble" and died on February 2, 1902 at the age of 72. They are both buried in the Mohr Cemetery in Hoaglin Township, on land purchased by Christian's father in 1862.
