Margaret Lumsden, nee Duncan, was the daughter of Thomas Duncan and Catherine Johnston. She married a lumbar baron, MPP for Ottawa, named Alexander Lumsden, who died Aug 5, 1904 while Margaret died Nov 27, 1906 in New Edinburg, District of Russell, Ontario, Canada.
Margaret had a brother Thomas who was born Nov 20, 1944 and nothing more is heard of Thomas after the 1861 census for Gloucester Township, when Thomas is age 16, a laborer.
Perhaps the obituary for Margaret would mention her brother Thomas if he is still alive and where.
Thanks for any help
