Hi Don
I am researching the McArthur family.
I have hit so many brick wall with this line of my research. I have a Soper and Cripps line in there as well, but my McArthur's seem to be hiding ....
Peter McArthur was born about 1812 in I believe Argyllshire Scotland.
Peter married Mar McEachern born May 1826 in Scotland, Mary emigrated to Canada 1840.
Mary Died & Dec 1902 in Acton Ontario, don't know where she is buried???
They had children
Peter who was born 1854 and died Dec 1906 in Acton Ontario, again don't know where he is buried.

Duncan (MacArthur) born Sept 1858, died Apr 1947, burial Fairview Cemetery Acton. Duncan married Hannah Dron in 1888 and had 10 children, Edna b-1888, Florence (May) b-1890, Robert (Frederick) b-1893, Jean (Jenny) b-1894, Christina b-1899, Theresa b-1899, Clarence b-1904, Helen b-1910, John b-1914 and Seina (Mac)(Cana) birth unknown.

Catherine McArthur was born 1864/71 and married Joseph Wesley Campbell in Jul 1893 Georgetown, Joseph died Aug 1897 and Catherine remarried James Hall in 1901. Catherine had children Christina McArthur b-1887, Ada b-1894, and Mary Ellen b-1896. Catherine and Joseph are buried together in Fairview Cemetery Acton.

What I am hoping to find is where Mary (McEachern) McArthur is buried?
With this info I most likely will know where Peter her husband is buried and also where her son Peter is buried.
Hope something here sounds a bit familiar to the info you have on McArthur's
