Lampard of Illinois

John Lampard, born May 1856 in England married Elizabeth (Last Name Unknow), born 1860 (est) in England. I believe they were married in the United States. They settled in Illinois. Children were: Percy, born 1891 and Authur, born 1900 in Illinois. Percy Lampard married my Grandmother's sister, Bessie Poole (born 1889 in England). They settled in Illinois and had one child. Looking for information on Elizabeth and other family members.
