They are listed in the 1910 census, Lake Co. Madison twp., Ohio. Albert Landreth is 50 yrs, Mary is 54, with sons Elmer and Roy Landreth. In the household are Pearl Hunt a stepson; Edna (his wife) stepdaughter; and Pearl Hunt stepgrandson. This is obviously Albert's second marriage, I have nothing of his first wife.
Think you may wish to check messages 490 and 571 this forum for someone who may be searching the same Landreth family. Good Luck, Fred
