|1940 Jackson (Michigan) City Directory|
They were largely in Jackson, Jackson, Michigan by 1940. John G. Allen (Sr.) above is my great-great-grandfather. Below him are his sons John S. and my great-grandfather, Jos(eph) J(ames). John G. Allen, Jr. is actually John S.'s son.
When the 1940 US Census is released in a little over three weeks I'll be using the above to find them. 1124 Scott St. will be in ED 38-50 in Jackson's 8th Ward, block 80. 207 W South will be in either 38-25 or 38-33. According to the map, it was a city limit boundary street in 1940.
