How it is shown: Complete page as held in the registry; no crop, no retouch.
Keep in mind: What the page says: household 338, lines 38-40; Herbert S. Clarkson is the informant and head, renting at $145 a month, 49, born Texas, 'Colonel, U.S. Army'; Ruth, wife, 48, housework, born Texas; Herbert K., son, 23, single, in school, born Texas; the 1935 residence column gives Fort Sill, Oklahoma, for the parents and Austin, Texas, for the son (a stated earlier residence, not an enumeration there). The street 'East Delaware Place' is read; house number 230 is Likely. Whether these are our people: Likely, from names, ages and birthplaces; the registry tags Ruth Joyce Kelso Clarkson, Herbert Slayden Clarkson and Herbert Kelso Clarkson, who are all deceased. The rest of the sheet lists unrelated households and is not described.
