The 1880 US Census places the John Thomas family living at 2626 Portland Avenue, Chicago. Living with John and his wife Bridget are their sons James, age 20 and Martin, age 17 and their youngest daughter, Lizzie (Lillian) age 11. Their oldest daughter, Bridget, married in 1878 and Mary Ellen married in 1877. Their son John, born in 1867, died on January 1, 1879, the year prior to the census.
John Thomas is still listed as a laborer and Bridget is listed as keeping house. James and his brother Martin are both working in a packing house, most likely in or near the Chicago Stockyards. Lizzie is currently attending school.
There are two other "families" living at 2626 Portland leading one to believe the Thomases are living in and renting in a two or three flat building.
