Trying to find a marriage between John Gustav Rewers and Clara ?. He married Charlotte Liston in 1891; my grandfather and a sister who lived only a year born 1892 and 1895. Charlotte passed away aged 41 yrs. in 1905. Clara had known her. (I was originally told she was a sister). So marriage 1906 or a little later. The Rewers family emigrated to Ontario Canada before 1910.
Would appreciate any help with marriage lookup and finding last name of Clara.
