Hi, gang. I am looking for any connection to my great grandparents. They are listed in the 1920 Census as: John Weir, age 36, born in Illinois and married to Bertha, age 34, born in Germany, (NR-what does that mean-NR). They had two sons, Howard, age 11 and Arthur, age 7. If anyone can help, I surely appreciate it. Any suggestions? Thanks, Laura
