I was named after my father, and my name is Robert _____, Jr. To distinguish us, his name was written Robert _____, Sr.
My sister recently announced her daughter's (my niece's) engagement, and the article stated that my niece was the granddaughter of Robert _____. The abbreviated word "Sr.) was not listed as part of his name.
This announcement occurred in the small town where we all grew up, and some people, including me, are wondering why Sr. was not added to the announcement to distinguish his identity from mine.
