Thanks for your response. The information that I have that Mary McTavish McVeety and Mary McVeety Anderson died young is from a letter written by my great aunt Jean McTavish Anderson Brown in the 1960's to a cousin, James McAndrews. She may have been a little confused. Mary McVeety and John Anderson 1839-1930 had six children as follows:
Helen Anderson 1885-1947 ( my grandmother ) who married Montagu Arthur Shipman 1879- 1969 and had three children, Elmore Ernest Montague Shipman ( my father ) 1907-1978, Helen Jean Burt Shipman 1914-2000 and my uncle who is still alive.
Jean McTavish Anderson about 1885-1966 who married W. Leonard Brown about 1880-1935 and had two daughters Hope 1910 to about 1995 and Margaret 1907-1971.
Mary Anderson about 1885-1947 who never married.
Christina Lamont Anderson about 1885- 1945 who married Stewart C. Lowden and had three sons and seven daughters including Jack, Margaret and Irene.
William Anderson ( no information )
Duncan Alexander Anderson ( no information )
Helen and Jean and their families moved from Ontario to Pasadena, California about 1912-1917. The rest of the siblings stayed in Canada.
Are you a descendant of Thomas X. McVeety and Isabella? I have some information on their family from the LDS records.
