Elizabeth (BEARD) HILLMAN--Wm BEARD ENG>IA>KS>OR

I am looking for information on William BEARD and Mary (BRISTOW) BEARD both born in London, England.They are the parents of Elizabeth BEARD HILLMAN, who is my great grandmother. Elizabeth BEARD married Samuel Theodore HILLMAN, 20 Sept 1873 in IA, and shortly after moved to Beloit, KS and they had 9 children -- 2 were born in OR(one was Theodore Fremont HILLMAN, and he had 6 children, one was my father George Fremont HILLMAN.) Samuel Theodore, and Elizabeth (BEARD) HILLMAN are both buried in Shedd, Linn County, OR at the Shedd Cemetery (formerly Pugh Family Farm and Cemetery.)The family of Samuel T. HILLMAN lived in Beloit, KS before moving to Oregon in 1889. Elizabeth BEARD was born in Bonparte, IA 19 Mar 1853 died 30 Sept 1937. I once retreived a gedcom that listed Elizabeth as having a surname of Weir, and this is incorrect, because I have her death certificate, and obit, (as well as an article written in Families of the Willamette Valley copyrighted 1903 that listed Samuel T. HILLMAN and ancestors and descendants. Elizabeth was listed as "BEARD."
If anyone can help me please email me directly.
