Christian Mosier was the great-grandfather of Florence Mosier and one of four children of Frederick Moser and Elizabeth Smith. Family records indicate that Christian was born on October 11, 1820 in Greenville, Indiana. This is supported by the 1850 Census for Georgetown, Floyd County in which Christian indicated that he was 29 years of age and that he was born in Indiana. Greenville and Georgetown are both in Floyd County and are less than ten miles from each other.

On September 22, 1842, Christian married Sarah ("Sally") Burger. Record of their marriage is included in Floyd County Marriage Records, Vol. B. May 1837 - May 1845 and indicates they were married by Henry Bonebrake, a minister of the United Brethren Church in Georgetown. Christian's surname is shown as "Moser" in both this record and the 1850 U.S. Census. Christian and Sarah had four children in 1850: Sarah (age 6), Mary Jane (age 4), Elvira (age 2), and an unnamed infant girl (age 3 months.) Real estate owned by Christian was valued at $180.

Sophronia Blair was included in the 1850 Census with the household of Frederick Wolf, also of Georgetown, Floyd County. The Wolf household included his wife, Martha Jane, and six children, ranging in age from 11 years to 11 months. Alexander Sampson, age 22, was also listed as a member of the Wolf household and was probably working for Mr. Wolf. Sophronia Blair indicated that she was 18 years old and that she was born in Indiana. It is possible that Sophronia was a relative of the Wolfs or that she was employed by them to assist with care of the children. It is thought that Sophronia was born in Harrison County, Indiana which is adjacent to Floyd County. Her parents are unknown. A Joseph Blair was listed in the 1840 Census for Harrison Township and is the only Blair listed in either Harrison or Floyd County for this census. It may be that Joseph Blair is Sophronia's father.

Both the Wolf Household and the Moser Household were recorded in the 1850 Census on the same day (September 10) by the same census-taker, and the Mosers were the sixth household visited after the Wolfs. Christian Moser's occupation was listed as "Shoemaker" and Frederick Wolf was listed as a "Cooper" or barrelmaker. It is likely that the two families resided near each other.

It is assumed that Sarah Burger died between 1850 and 1857 because on June 7, 1857, Christian married Sophronia Blair. Their marriage license, issued June 4, and the certificate indicating they were married on June 7 by Walter Moore are included in Floyd County Marriage Records Vol. C May 1853 - Dec 1857. These documents show that Christian's surname was now spelled "Mosier".

It should be noted that Christian was able to sign his name. A document in the land records of Floyd County dated March 9, 1846 and bearing his signature shows that he spelled his name "Moser." After 1852, however, available records indicate that he consistently used the spelling "Mosier," as did his brothers John and David.

The 1860 Census for Georgetown, Floyd County, Indiana records Christian Mosier and his wife Sophronia on June 2, 1860 with children: Mary (age 14), Alvira (age 12), Catherine (age 10), John (age 1), and Henry (age 3 months). All but John and Henry would have been Christian's children from his first marriage to Sarah Burger. Another John Mosier was listed in this household at age 16; he was not included in the 1850 census and might have been a nephew or an adopted son. The 1860 Census indicates that Christian's occupation was now that of "Grocer". Real Estate owned by Christian was valued at $600, and his personal estate was also valued at $600.

The 1870 Census shows that the Mosier family had relocated to Greenville, Indiana --about ten miles from Georgetown, but still in Floyd County. Christian was 50 at this time, and Sophronia was 37. Christian's occupation was shown as "Grocery and Coffee House" and Sophronia's as "Keeping House." The value of Christian's real estate had increased to $2,000 and his personal estate was valued at $1,200. Christian's older children from his first marriage were no longer members of the household, but he and Sophronia now had eight children of their own: John S. (age 11), Henry C. (age 10), William F. (age 8), Emma B. (age 6), Charles M. (age 4), David P. (age 3), Hattie M. (age 1) and Martha V. (age 5 months). John, Henry, William, and Emma had all attended school within the year, but it was indicated that Henry "Cannot write". The 1870 Census also lists Martha Blair (age 48) as a member of the Mosier household. Martha indicated that she was born in Virginia, and it is possible that she was related to Sophronia --perhaps an older sister. Her occupation was listed as "House Keeper".

The 1880 Census shows that Christian (age 59) and Sophronia Mosier (age 46) are still in Greenville, Indiana. Christian's occupation is now listed as "Hotel Proprietor," and Sophronia is still "Keeping House." Birthplace of parents is information included for the first time in the 1880 Census. Christian indicates that both parents were born in Indiana; however, this is incorrect. Although they married in Indiana, Christian's mother and father were both born in North Carolina. Sophronia states that both her parents were born in Virginia. Children listed in the Mosier household in 1880 are: John S. (age 21, a laborer), William (age 19, a barber), Emma B. (age 16), Charles M. (age 14), Daniel P. (age 13), Hattie M. (age 11), Martha V. (age 9) and Florence (age 7). Son Henry C. is not listed with this household and cannot be located elsewhere in the 1880 Census. Martha Blair is listed in the 1880 Census for Greenville as a servant in the household of an elderly couple, Peter and Susan Seusenay; she indicates that her father was born in Virginia and that her mother was born in Tennessee.

The General Index of Deeds in Floyd County, Indiana for the period 1843 through 1882 includes twenty-eight transactions for purchase or sale of land by Christian Mosier. Through 1861, he purchased parcels on Main Street in Georgetown, all of which he sold before 1866. Between 1864 and 1873, he purchased and then sold parcels on Main Street in Galena. Beginning in 1874, he purchased parcels on Main Street and Harrison Street in Greenville. Given the fact that he is described as a "Hotel Proprietor" in the 1880 Census, it is likely that he bought land in Greenville to build his hotel. Christian Mosier last appears in the deed records on March 11, 1882. Sophronia Mosier is recorded as the purchaser of parcels in Greenville in 1887 and 1888. In 1889, Sophronia is recorded as selling a Greenville parcel to her son Charles M. Mosier.
