Looking for info about gt grandparents William Paull and Margaret McCormick Paull. Immigrated to the US around 1872. Children were John, Anna, Alexander, William and Charles. John and/or Anna possibly born in Scotland. The rest born in the US. Margaret may have been a circus performer. John joined the Barnum and Bailey Circus as a dancer around 1886. Later, John, Alexander and William performed in vaudeville as the Paull Brothers and travelled the Keith Circuit. Am interested in any information about where the family originated in Scotland. Thanks for any help.
