Through my great grandmother's journals (Jessie (Tucker) Agard) and documents have I been given, I've learned a lot more about her sister, Adelaide.
Adelaide Tucker (7 April 1871–5 April 1960) was the second daughter of William and Fanny Adelia (Hosner) Tucker. Addie grew up in Enfield, Tompkins County, New York. She matriculated at Cortland Normal State Teachers College (Cortland, NY), and upon graduation Addie taught first in Ramapo, Rockland County, New York, and then, by 1910, and for the rest of her career in Asbury Park, New Jersey. From 1920 through 1930 while continuing her teaching career she boarded with Cornelia Thompson in Asbury Park, New Jersey. Although eleven years difference in age, a close friendship developed between Addie and Cornelia, and in 1924 Cornelia accompanied Addie to Jacksonville for the summer.
Cornelia B. Thompson was born 11 May 1860 in New Jersey. In 1940 Cornelia and Addie lived at 126 South Main Street, Ocean Grove, Monmouth County, New Jersey. Cornelia died 2 December 1940 and is buried in Maplewood Cemetery, Freehold, Monmouth County, New Jersey. 
When Addie traveled back to Jacksonville during her school vacations, she took the Black Diamond train to the Willow Creek station, and in later years got off at the Ithaca, NY station.
When she retired from teaching, which was between 1944 and 1947, Addie made her home back in Jacksonville and Trumansburg, living with her sisters. She kept busy helping her sisters with their household chores, grocery shopping, and caring for family members.
In late December 1959 she moved her things from Jessie and Arthur’s house across the road to Bill and Marian Agard’s home while Jessie and Arthur spent the winter in Florida with Louie and Adeline Tamburino. In March 1960, Jessie received word that Addie was not feeling well. Jessie so wished she could be back in New York to care for her sister. Every few days Bill and Marian reported on Addie’s condition. She continued to fail. Shortly after Jessie and Arthur returned home, Addie was in very poor health, and by March 28 they admitted her to Mrs. Leonard’s nursing home in Jacksonville, New York. On April 5, just two days before her 89th birthday, at 5:30 a.m. Addie Tucker passed.
