Not related, found this of interest and did a little research.
In 1900 The family is listed as follows in Wood Co., TX
Kilcrease, Lucy 6/1776 NC NC NC 5 children 1 living Luncford, Marthy Born July (no year) Georgia NC NC King, Isabell Jan 1862 Alabama Georgia Georgia
I found it interesting that I could not find them in any census listed as above, anywhere, but in my search I found the following:
1880 Cotton Hill Barbour Co., Alabama
Gilchrist, Lucy age 56 born in NC with parents in NC listed as wife (no head listed) Gilchrist, Mary C. age 30 GA NC NC King, Martha C. age 29 GA NC NC King, Isabella age 14 Ala GA GA
(the age for Martha is transcribed as 29 but could be 39 with Mary being 31, tough to read on the handwritten census)
1870 Barbour Co., Alabama
Gilchrist, Lucy age 52 Georgia King, Martha age 29 Georgia King, Pitman age 11 Alabama King, Isabella age 6 Alabama
1860 Barbour Co., Alabama Gilchrist, Lucy age 40 Gilchrist, Catherine age 18 Gilchrist, Solomon age 16 Gilchrist, Theold age 14
1850 Barbour Alabama Gilchrist, Lucy age 35 Gilchrist, Martha age 9 Gilchrist, Catherine age 7 Gilchrist, Solomon age 6 Gilchrist, Thielder age 4
I did find a Lunsford family tree online that has Lucy's maiden name as Worsley. The last child is listed as Sarah Theola Gilchrist and the tree shows her married to a Stephen Sol Lunsford. The Lunsford name appears in many of the census living nearby the Gilchrist family.The Lunsford tree put an approximate death year of 1900 for Lucy and stated that she probably died in Alabama (no documentation). It also lists Martha as Martha Catherine Gilchrist.
Not sure that I have found the right people, names and ages seem to fit. Certainly an interesting family to follow.
