This would be my great grandmother, Elsie M Kishpaugh Ike (from Eike)married to Isaac A (Isade A)Ike, 1824-1906.
Their daughter, my grandmother, was also Elsie (Ann) Ike, 1891-1983, married to Howard Searing Davenport.
The Kishpaugh name was misspelled, perhaps intentionally, in the Whitney biography (Richard Whitney who married Laura C Ike, sister to my grandmother) as Kaussbh, but it is Kishpaugh taken from her tombstone in the Locust Hill Cemetery, Dover, New Jersey.
The powder plant explosion took place much later, in the early 1940'S and that Elsie M Kishpaugh Ike was not killed in it. At the time my mother was living with my paternal grandparents while my father served overseas in WWII, so this was something I heard of directly from both my mother and my paternal grandparents.
