I am not an Alexander researcher but I have in my book,"Forebears and Descendants of Landreth Pioneers", a good record of Alexanders who went from Dubois Co IN to Ypsilanti MI. I will be glad to share what I have. From my book I show the following:
AMERICA LANDRETH b. Dubois Co IN 2 NOV 1877 d. of a massive stroke 19 NOV 1941 m. in IN 1896 IRA ALEXANDER b. Jasper IN 16 APR 1876 d. 23 JUN 1952. After their children were grown they moved to Ypsilanti MI 23 SEP 1926. Both d. there and were buried there in Highland Cemetery.
America Landreth was a dau of JOHN WELLS LANDRETH & ELIZABETH BEATY. I have many descendants of America and Ira. I have a good record of the Landreths back to 1580 in Scotland..............Eugene Landreth
