Quiz on how to read the census

This is a simple quiz. Multiple Choice. I am going to provide you with data on a family from a series of census forms, as well as two draft registrations, and then ask one question. The data includes names, places of birth, birth years, and the relationships provided on the census. Most of the names below have been changed.

Larry (1886 Russia)
Peggy (1884 Russia)
Sarah (1894 Missouri)
Hugh (1896 Missouri)

1910 – St. Louis
Residence 1:
Parents: Jim and Jane (Russia)

Hugh (1897 Missouri)

1920 – Chicago

Living with Unknown family

Residence 2

Brenda (1920-Illinois) Daughter

1918 WWI Draft Registration
Larry – Married
Hugh - Single

Question: Who is Brenda’s father?
A. Larry
B. Hugh
C. Not enough information

Yes, it certainly looks like in 1920, siblings Larry, Sarah, and Hugh are all living together, and there is actually only one wife, and the census taker got it wrong.

Or possibly there is a second Sarah but since Hugh and Sarah are together in 1930, Suzy and Larry were the other couple.

In 1930 either husband/wife or siblings Hugh and Sarah are still living together, and Suzy – the definite newcomer to the family from 1920 is alone with her daughter. So Larry is the father, right?

Well, if you answer that way, congratulations, like I was, you’re wrong.
The answer should be C. (Or B if somehow you're psychic) Because Brenda is still alive, and insists her father is Hugh. I’m willing to accept this statement. Especially since I am told that Hugh went through five wives, and Brenda was raised by her mother.

I think there are three Sarahs – a sister and two wives. All born in Missouri about the same time.

I think in 1920 Larry was married to the second Sarah, and Hugh to Suzy.
I think in 1930 Hugh was now married to the third Sarah, and Suzy was raising Brenda.

The sister Sarah probably married someone prior to 1920.

I'm glad I found Brenda -- hopefully she can straighten this mess out.

Genealogy Challenges and Puzzles

I've been having fun with Genealogue's challenges, but I often see them after the answers are revealed in the comments, or while I am at work without much time to solve them. I did submit one to him, and it was fun to see people solve it.

A local puzzler named Nobody published a puzzle late last night early this morning, and today it has a genealogy-related slant. I found it not too challenging, but still somewhat fun, since it involved some well-known names, and thought others might like to try their hand.

Nobody's site used to be much more active than it is now, but it's good to see they're not completely gone.
