Andrew Robert More was the fourth child and second son born to Andrew Robert More and Jeanette Allan Weir. He was born near Hamilton, Scotland in Lanarkshire County in April of 1845.

He was only five when he left Scotland on the ship "Liberty" with his four siblings and parents to journey to America. He lived with them first in Waukesha County, Wisconsin and then in Jefferson County, Wisconsin before they made their last move via covered wagon to their settlement in Pilot Grove Township in Faribault County, Minnesota in the spring of 1858. As a youth, he would have had many stories to tell of their journeys when he got older.

On the 1860 Federal Census, he was a lad of 14 living in Pilot Grove Township on the family settlement with his parents and six siblings.

There was much unrest among the Sioux Indians in 1862, and they were attacking settlers and killing many. He was 17 years old when he volunteered on October 21, 1862 to be part of Company K Mounted Rangers during the Indian Wars, and held the rank of Private. He was discharged on December 10, 1863. He had served with two of his brother-on-laws in that conflict.

The next year on March 26, 1864, he became part of the Civil War on the Union Side as part of Company B Brackett's Calvary Battalion and was discharged on June 1, 1866.

By the 1870 Federal Census, Andrew was a single farmer living with his parents and three siblings on the home farm in Pilot Grove Township. At age 25, he married Matilda Ann Dillman (1856 - 1944) on January 30, 1871 in Faribault County, Minnesota. She was the daughter of Frances Michael Dillman and Susan Miller, her father a farmer in Faribault County at the time.

On the 1875 Minnesota State Census, he and his wife were living in the city of Blue Earth, and had two children (Frank 2 and Janette 1) living in the household with them. By the 1880 Federal Census, he was living in the city of Blue Earth, Minnesota, with an occupation of being a photographer. This would have been an unusual occupation at this time and a very different career path than the rest of the family. With him in the household were his wife and two children (Frank and Jeanette). An old city directory in Blue Earth revealed that he was involved in the photography business with a partnership in More and Hager Photographers, and were said to be stereograph photographs.

On the 1885 Minnesota State Census, Andrew and his wife were still living in Blue Earth with three children. However, by the 1895 Minnesota State Census, they only had two children as one child had died (Jeanette or "Jessie" as they called her).

On the 1900 Federal Census, Andrew was farming again (likely as his father was perhaps in aging health and his brothers were farming lots of land and needed lots of help with it). In the household were his wife and daughter (Susan 19), who was a painter. Additionally, in the household was Ruth McLeod, a niece working as a printer, and Elwin More, a nephew working as a jeweler. They may have been living with them since Andrew and his wife lived in the city where they both worked. On the 1905 Minnesota State Census, Andrew was still said to be a farmer and living on East 8th Street in the city of Blue Earth, Minnesota.

By the 1910 Federal Census, Andrew was living in Blue Earth and at that time was said to be Hotel Innkeeper. Only his wife was living with him at that time.

By the 1920 Federal Census, Andrew was still living at the same address in Blue Earth. He was age 74 and likely retired as no occupation was listed for him. The same was the case for the 1930 Federal census.

Andrew Robert More Jr died on August 25, 1932 at age 87 in Blue Earth, Minnesota. He was buried in Riverside Cemetery in Blue Earth, Minnesota. His wife, Matilda, continued to live in Blue Earth on East 8th Street, and was there on the 1940 Federal Census listed as a widow. She died on March 13, 1944 at age 87 and was buried next to Andrew in Riverside Cemetery.
