Saerching for descendents of John Armstrong who married Missouri Armstrong about 1870 in Arkansas. They appear on the Collin county 1880 census with children Booth age 5 born in AR and Anna age 2 born in TX. I had an email from a lady that said she had seen a Missouri Armstrong buried in a small cemetary down a country road in the Little Elm, Colony area, atop a hill. Would really like to know about this. Thank you. Eve
