Mamie Dorr was the first child of John Adam Dorr and his wife Ellen A. Hayes. She was baptised Mary Dorr, October 31, 1880 at St. Anthony of Padua Catholic Church, 813 Main St. Minneapolis, MN. (church is about 3 miles SSW of the cemetery). Her sponsors were Daniel and Anna Hayes- officiating priest was Father Felix Tissot.

Her folk's had married July 8, 1879 and lived in the Irish neighborhoods near St. Anthony Church.

Mamie died of unknown causes May 28, 1881 at age seven months and was interred in grave 2 of the five grave plot her folk's purchased at St. Anthony Cemetery. Seventeen years later, her grandfather, Tom Hayes, was interred next to her on the southside in grave 3.

John Adam and Ellen were surely devastated at the lost of their girl, their first born child. Soon after the birth of a son the following spring and a daughter two years later, they relocated themselves from the city to Oneka Township, Washington County, Hugo Minnesota and opened a farm. Their 80 acre farm was approximately 20 miles northeast of St. Anthony Church near White Bear Lake, MN. After moving to the farm, they had 9 more children, the youngest born in 1906, 7 daughters (including Mamie) and 5 sons. They lost a second infant daughter in 1889 at birth.

The family may have never used the remaining three open grave spots in St. Anthony Cemetery. Cemetery records are confusing. There are two confirmed burials in the five grave plot (Mamie Dorr and Tom Hayes), yet the record book, the sexton's grave assignment book, claims the plot is full. Perhaps Ellen Dorr's sister Annie Hayes Russell, 1866-1885, is buried unrecorded in one of them, however, the cemetery records her grave as the only interment in a five grave plot adjacent to the east. There are no grave markers for Mamie or Tom Hayes, however adjacent to them on the west is a large Hayes monument with unmarked graves of Tom Hayes' brother James and his family and marked graves of Martin Hayes and his family. Martin Hayes is an unknown relative. Tom Hayes 1828-1898, his brother James Hayes 1830-1887 and oldest brother Dan Hayes 1825-1902 all lived and worked in northeast Minneapolis. All three Ireland born Hayes brothers are buried in St. Anthony Cemetery located at 2730 Central Ave. NE., Minneapolis, MN written by Gregory Dorr
