Sorry it took so long,
If this is the same Frederick wheeler/rouette yes there was a sister named amelia, but I don't show a ellen, Frederick's mother was Marie LaWere from canada, The father was Levi Rouette/Wheeler. There was 7 children to Lawere and Rouette, but I wrote to rouses point and they only had records from 1891 and forward , so Im still searching for birth certificates, They told me to check with Champlain. But can't find a address to write to. I hope this helps you. Can you let me know what kind of information that you have?
