Hi, I looked on ancestry.com and didn't find any McFarlands on a census in Montgomery county in that time period, but they didn't have the 1840 Republic of Texas census. >From the 'Texas tax list index 1840-1849': Andrew Jackson McFarland, Fannin County, 1845 Rebecca McFarland, Fannin County, 1843 William McFarland, Harris County, 1849 J.B. McFarland, Nacogdoches County, 1841 >From the 'Texas tax list index 1830-1839': Nancy A. McFarland, Austin County, 1834 and 1838 Thomas S. McFarland, Nacogdoches County, 1838 James McFarland, San Augustine County, 1835 and 1838 Simie McFarland, San Augustine County, 1835 and 1838 Thomas McFarland, San Augustine County, 1835 and 1838 William McFarland, San Augustine County, 1835 and 1838 In the 'Texas land title abstracts' they had 29 McFarlands including this one: District: Montgomery County: Walker Grantee: James P. McFarland Certificate: 3913 Patentee: James P. McFarland Patent Date: 11 Feb 1846 Patent #: 360 Patent Volume: 3 Acres: 320 Class: Mont. Bty. File: 82 Hope this helps.
