[Home] [Robert Mackay Clan Links and Information] [The Origins of William McKay & Family]The Origins of William McKay & Family (Page 4)probate file, but there is no specific information in the probate file to explain what happened to the 3 other slaves (Harriet & two infant girls). However, the names, ages and genders in the 1849 inventories provide the means to identify the remaining slaves listed in the Slave Schedules of 1850 and 1860. In the 1850 Slave Schedule for "John W. Keizer", the 3 slaves can now be identified as:
A bill in the probate file to the James M. McKay estate for medical, funeral and burial costs shows that Margaretha died of illness in April 1852. In the 1860 Slave Schedule for "Mary Ann McCay", the two remaining slaves can now be identified as:
I have no further information for Elisa (Eliza) after she appeared in the 1860 Slave Schedule along with William. However, it is interesting to note the 1850 and 1860 census schedules for John & Rosina Keiser show a daughter named Eliza whose age range is the same as the slave Elisa. Based upon U.S. Census records, a public genealogy tree and Missouri death certificates, Mary Ann McKay married Rudolph Hillenkamp around 1863 and they continued to live in Dardenne Township in St. Charles County in a community called Cottleville. They had 6 children between 1864 and 1884. Rudolph died in 1909 and Mary Ann McKay Hillenkamp died in 1917 at approximately age 75. As stated earlier, John W. Keiser and Rosina were both German immigrants. Rosina Pfaar McKay Keiser was born in 1821 or 1822 in Bavaria. A record for a passenger ship called "Merchant" shows that she and her parents and siblings departed from Le Havre and arrived in New York in 1837. She married James McKay in October 1841 and a year after his death in February 1842, she married John Keiser in February 1843. They had at least 8 children from 1844 to 1865. Upon his marriage to Rosina, John Keiser became the "administrator de bonis" of the estate of James McKay and served as Mary Ann McKay's guardian until July 1863 when Mary Ann reached age 21 and/or married. During that time, he collected monies due the estate and paid outstanding debts including the bills for James M. McKay's medicine, doctor's visits and his coffin. The last county tax receipt in the probate file is dated December 10, 1857 and shows an assessed value of $500 for slaves and $1,300 for the 240 acres of land. With the approval of the probate court, Keiser paid himself a fee for his administrative duties and he also charged the estate for the care and boarding of Mary Ann McKay as well as for 'keeping, boarding and clothing of Negro children.' John W. Keiser died in 1878 at approximately age 58. Rosina Keiser appeared in the 1880 census and she died January 28, 1892 according to her grave stone at U.C.C. Cemetery at Weldon Spring in St. Charles.
