According to the City of Rochester archives site, Edwin John Bieder married Alice E. Summers in 1888. Here is the link:
I did not see the second marriage to Florence indexed.
In 1900, "Edward Bieder", married, is living alone in 3WD of Roch. By 1910 he is married to Florence (7yrs) and living on S. Fitzhugh St. in Rochester.
Hope this helps,
