VINEGAR, Rachel
1 male between 15 - 19 b. bet 1811-1815

1 female between 5 - 9 b. bet 1821 - 1825
1 female between 40 - 49 b. bet 1781-1790
(Rachel is listed above John Solts in the 1830 census. It is thought that Rachel was a Salts and that she married a Brinegar.)

From this book I have, East Tennessee Tax Records Index: Washington County, 1822-1839.
Brinegar was not listed in the tax records.

So from this it appears that David died in 1830. He is not listed in the 1830 census. It also appears they had a son named James and may have had a daughter named Rebecca. Or are Rachel and Rebecca the same person?

The 1830 WACO census lists:
Rachael Vinegar
1 male 15-19  b.1811-1815
1 male 20-29  b. 1801-1810    probably James
1 female 5-9   b. 1821-1825  (a change of life baby)  Rebecca??
1 female 40-49  b. 1781-1790   Rachael

The 1840 census ages Rachel 20 years from 1830
Rachel Vinegar
1 male 20-29
1 female 15-19
1 female 60-69    b. 1771-1780
