I need to bring this thread full circle. Emma Coster was not my Emma.
My Emma was Sarah Emma Resler Dolan nee Taylor b 1862 in Grant Co, IN of Robert and Rebecca Taylor. In 1880 she had dau Jennie Resler nee Tayor. In 1884 she married George Resler in Jay Co, IN. In 1899 she married John (Jack) Dolan (shown as Dohan) in Grant Co, IN.
Much of this is noted in related posts and my LRayVick1 tree on Ancestry.
See my latest post in the TAYLOR family or in this Grant County section for ideas on the ancestry of her father Robert Taylor (his wife was Rebecca Caylor).
