For many years, Thomas' identity was a mystery. My Uncle Bob had done significant research (he even hired two professional genealogists) and was unable to find Thomas' name. Instead, they found his wife, Sary in Madison County, VA. She appears on a census record as living with her children, which leads me to believe that Thomas preceeded her in death. This census is the last listing of her I can find. Thomas appears in no census for the US.
In 2002, I visited the Madison County VA courthouse, where I obtained copies of all the Gallihugh related marriage licenses. Attached to two of the licenses, there are handwritten notes from Sarah Gallihue, requesting the court to issue a license to her daughters Hannah and Nancy. Both documents are signed (with an X) by a Thomas Gallihue, whom I presume to be Sarah's husband because it was customary back then (early 1800's) for the father to sign a marriage license for his daughter (brides did not sign the papers, only their grooms and fathers did). As a result, I have added Thomas as Sarah's husband and will continue to research this lead.
In February, 2011, my dad discovered a posting for a Sary and Moses Gallihugh, who were married in Glasgow, Scotland in 1779. They are listed with the same children as the Sary and Thomas in my records. Since I cannot view the original document, I'm going to assume that there was a transcription error and the husband's name is Thomas (or perhaps Moses was a first or middle name). But, regardless, this appears to be the original Gallihugh family posted on this website, who immigrated to the US before their first child, Nancy, was born. Moses (Thomas) is listed as having been born before 1765 in Glasgow, Scotland. I'm still searching for documentation of their entry into the United States.
The earliest surviving Census for Madison County in Virginia is 1810. The only Gallihugh/Gallehugh/Gallohugh household in the state of Virginia in 1810 is that of Sary (Sarah) Gallohugh. The 1810 Census indicates: 2 females 16-26, 1 male 16-22, 2 males 10-16, 1 male under 10, 1 female over 45, and 2 slaves. It appears highly probable that the 1810 Census included Nancy, Hannah, Elijah, Moses, ?Marion, and Isaac, plus Sary, since the six dates correspond so closely to the dates of the children.
The only early Gallihugh record reveals the marriage of John Gallohue to Ann Rowe on 23 Feb 1793 in Culpeper County, Virginia. This could be the Ann Gullehugh on the 1840 Madison County, Virginia Census; however, there is no proof. Culpeper County and Madison County are adjacent to one another. There is no more trace of John in the records of this area. There are no other early Gallihugh/Gallehugh/Gallohugh men in this area's records.
Sary Gallohugh is not listed on the 1830 Census, consequently, she could have passed away or have been living in some other household, such as that of one of her children.
