I found the descendants of Phillip D. Rolli(n)son on the internet sometime back while looking for my branch of the family.I have the entire tree on diskette somewhere and I will e-mail it to you when I find it.Briefly, Phillip and Emma married 9/23/1886 in Lovettsville.She was the daughter of Isaiah Virts and Mary Cooper.Philip and Emma had 10 children:Carl P. 1890-1965; Sadie L 1893-1974; Evelyn Myrtle 1894-?; George Elgan 1894-1992; Ella Elizabeth 1899-1981; John Thomas 1901-1986; Zebulon I. 1903-1991; Edgar M. 1905-1990; Charles Raymond 1907-1971 and Nellie R. 1911-?.I have documentation references for some of this info.
According to the information I have, Ella Elizabeth married Baker who died before 1920.She married Warden W. Werking.She had one child Raymond Leslie by her first husband and six children by the second.
If I don't find the diskette, I will scan the printed pages and send them to you.
