Robert Boyd Brown(e) in Illinois and Michigan

I am searching for info on Robert Boyd Brown, or Browne, who was born in Michigan (probably Sturgis, St. Joseph County) in 1869.His parents were Rev. Hugh W Brown and Almira Van Dooser.He married 1st. Emily G. Bell in Morgan Park near Chicago, IL in 1898 and 2nd. Bertha M. Johnson on 31 Oct 1921 in Detroit, MI.His marriage record lists Bertha's parents as August Johnson and Hilda Larson.

In the first marriage he is listed as R. Boyd Browne and in the second he is listed as Robert B Brown.He was named for Reverend Robert Boyd who baptised his father, Hugh W. Brown, in London, Ontario in 1851 so I am fairly sure these marriages are the same man.

Robert and Emily Browne are listed in the 1910 Cook County census.I find nothing later for Robert after his second marriage.

August Johnson and wife Hilda are listed in the 1930 Antrim County, Michigan census along with 3 grandchildren ... Robert, Bruce and Betty Jane Browne.Note the spelling.I can't find the census listing for Robert and Bertha.

Bertha M. Browne is buried in Lake View Cemetery in East Port, Michigan, along with son Bruce A. Browne and daughter Betty Jane Browne Convery.I would love to find the death info for Robert Boyd Browne, Sr.

Any info on this Browne would be greatly appreciated.
