Yes, Daniel had a brother named David. Daniel would have been born around 1866 or 1867, and David around 1868 or 1869. I have found them first on the 1870 census in Wood County, Texas. Their parents were J. W. and Sarah Crow, and there were four other children (Seaburn, Mary, Elizabeth, and Naomi) shown on the census who were children from Sarah's previous marriage. The 1880 census shows J. W., Sarah, Daniel, and David living in Upshur Co., Texas. The 1900 Census shows James W., Sarah, and a female named Aleitha who was born in 1870 and listed as their daughter.
