Another Brown family from Scotland

My great grandmother was Isabelle Stone Brown, born Dec. 22, 1891 in Scotland. She married William Jackson Kennedy on Feb. 1, 1916, in Bonhill Scotland. She had 2 daughters with William, Elizabeth Margaret Kennedy, 1919-2001, and Dorothy J Kennedy (Czirok), 1920- still living. In 1923, Isabelle immigrated with her daughters to America, to be followed by William. From there, they continued to live in Lincoln Park, Michigan.
Her parents are William Brown and his wife, Margaret Stone. Isabelle did have one sibling, a brother named James W. Brown.

Does anyone recognize this family and have any other information on them (previous family)?

Thank you,
Julie
