I was able to find a little more information regarding my initial post. I found Lina Olmsted/Olmstead-Gyger remarried after her husband, Edwin Gyger, died. Lina married Samuel Burnell of LaSalle Co, IL in 1897.
Furthermore, Phebe's maiden name was Havlin. She married Edgar S. Olmstead/Olmstead. He was born in 1822 and died in Neponset, Bureau Co., IL in 1898.
If anyone has anything further they could add, it would be greatly appreciated.
