Upon returning from a year long working holiday, Alberta, the youngest of 4 sisters, announced her whirlwind marriage. Her 3 sisters, Carla, Paula, and Roberta, were amazed by her husband’s name.
The 4 men are Albert, Carl, Paul, and Robert. Their last names are Albertson, Carlson, Paulson, and Robertson.
No woman’s husband has a first name that consists of her first name without the final “a”; no woman’s last name consists of her first name without the final “a” and with “son” on the end; and, no man’s last name consists of his first name with “son” added at the end.
Paul is not married to Roberta, and Robert is not married to Paula.
No husband and wife have “bert” in both their first names, but there is a man who has “bert” in his first and last names.
Carl’s last name is not Paulson.
