Searching for Walls family from Freehall, Aghanloo in 1901

Hi everyone,

In researching my family tree, I found that my great grandfather John Henry Walls came from Limavady. He came to America in 1910 but I'm trying to find out about my other relatives. His parents were William and Mary Walls, and he had two brothers (Henry and William) and two sisters (Maggie and Rosetta). According to the census records in 1911, his mother Mary (age 71) still lived with her son Henry (37) and daughter Rosetta (40) on Freehall Rd in Aghanloo, Derry. I believe his brother William (30) married a woman named Mary and they lived on Drumalief in 1911. And connection on information on this Walls family would be greatly appreciated!
