I am a descendent of the above and have also been looking for information on Mary Murdock. I believe she traveled from Kentucky to Brown County Illinois with her son William WheelerMcDannald, who was my G-Grandfather, after the death of her husband. William Wheeler had received 40 acres of land for fighting in the War of 1812. I think she is buried in Tucker Cemetary near Mt. Sterling,Illinois but I have not been able to verify that information yet. I see that your message was posted a while ago but am hopeful that you may have received some new facts that you would be wiling to share. I have William Wheeler's bible but there is no Mary Murdock listed there. i would love to know her history.
