Curtis Roan appears to be a child of Mrs. Lucinda (Burke) (Roan) Easley and one of her husbands, Spencer Roan(e).
1850 Marengo census: Lucinda Easly 37 VA Priscilla 6 AL Roane, Virginia 13 AL Curtis 12 AL
Marengo marriage records show Lucinda Roane married Edward Easley on 30 Nov 1841. and that Lucinda Burke had married Spencer Roan [sic] on 31 July 1835.
1840 Marengo Co., AL page 37, line 26 has Spencer Roane 1000011-10112. I believe that Lucinda was a second wife, and that her husband Spencer had previously appeared in King & Queen County, VA as follows: 1820, page 19, 200100-10200 1830 page 303 010101-11101
Another Marengo County marriage is that for Emily F. Roan to Francis F[oster] Hooper 17 July 1843. Emily was born 1822-1825 in Virginia. She may be the child aged 5-10 in the 1830 Spencer Roan home and the female aged 15-20 in the 1840 Spencer Roan home.
The Hoopers left Alabama before 1850 and are listed as follows in that census year: Francis F. Hooper household, 1850 Montgomery Co., TX page 31/63. "3 October 1850, #2/2 Hooper, Francis F. 38 KY merchant Emily F. 25 VA Mary Alice T. 10 AL Francis Foster 8 AL Roan, Martha Elen 19 VA." Martha Ellen Roan probably was a sister to Emily F. (Roan) Hooper and may have been listed as 0-5 in 1830, and 10-15 in 1840, within the Spencer Roan homes.
No Roans lived with the Hoopers in 1860 (when they were in Louisiana) but in 1870, they are as follows: 1870 Grimes Co., TX, Cortney P.O., 21 July 1870, page 288, #1253/1253 Hooper, Francis 58 KY farmer $200 Emily 48 VA Roan, Curtis 22 AL farm laborer
Curtis was no longer with the Hoopers in 1880, and the widowed Emily lived with a son. She indicated that her parents both were born in Virginia.
These facts suggest, but do not prove, that Curtis and Virginia Roan(e) were half-siblings of Martha Ellen and Emily F. Roan(e) and that all were children of Spencer ROan(e). This Spencer Roan probably was born around 1790-94 and likely died late in 1840 or in 1841.
Please note that I do not research the Roanes. My study of this group was only part of an effort to figure out who was living in the various HOoper households.
