The following information was written by Alice Proffer- Spillman, in her book entitled "A History of the Cape Co. & Stoddard Co. Proffer Family and its Antecedents and Descendants." (1976) (Ref 1)

“George Proffer Sr. was the son of John Proffer the pioneer of the family in Missouri. He was born in Pennsylvania in 1781 and moved from there to North Carolina with his parents where he grew up and got married. The name of his wife is unknown at this time.

Four sons were born to them in North Carolina before they came to Missouri, namely; Moses, b. 1810, Jacob, b. 1813, David, b. 1814, and Peter, b. 1816. Shortly after they arrived here in Missouri their fifth son, John, was born in January, 1819. It was between these years of 1816 and 1819 that this family came to Missouri.

In 1825 another son, George Proffer Jr. was born and finally in 1827 their daughter, named Adaline and called “Ada” was born. It seems the Mother did not live long enough to enjoy this daughter as she died shortly afterwards, either in 1827 or 1828, and George Proffer Sr. remarried on August 11, 1829 to Elizabeth Marney. To this union union three more children were born, Benjamin Franklin, Mahulda Elizabeth and William Washington Proffer. This made George Proffer Sr. the father of ten (10) children by his two marriages.

Although the exact date of George Proffer’s death is unknown, it is thought that he died around October or November of 1854, as papers on file in the Probate Court Office at Jackson, Mo. show that on November 10, 1854 his son, John Proffer, was appointed by the Court to administer his estate. A document on file there states that the names of the heirs of the deceased were as follows: ‘Elizabeth Proffer, his widow, and sons; Moses Proffer living in Stoddard Co., Jacob Proffer and David Proffer living in Cape Girardeau Co., Peter Proffer living in Stoddard Co., John Proffer, George Proffer, ‘Ada’ Adaline Proffer, daughter married to William C. Nance, and, the following minor children, Benjamin F. Proffer, Malda Elizabeth Proffer and William Washington Proffer, the last six residing in Cape Girardeau, Co.’

Although his burial place is unknown it is felt that he was buried in a family cemetery, sometimes referred to as the Proffer Cemetery and sometimes called the Link Cemetery, which is located on the farm owned by George Proffer Sr. at the time of his death. This cemetery was near the Snider Mill community and it has been abandoned and most of the tombstones destroyed.”
