Forgot to add that in the 1930 census, immediately next door to William and Jane Barr is their (now) married daughter Evelyn, married to a Mr. Maxwell and with an 8-mos-old son Allen. Enumerated with her is her brother-in-law Thomas, and her single siblings, Robert and Melba. Her husband is obviously away as she (or the census-taker) has answered all the questions as though the husband were home, putting down Thomas Maxwell as Evelyn's brother, and putting down Robert and Melba Barr as Evelyn's brother and sister-in-law.
