Seymour Savage

Seymour Savage was born to Lottie Savage, a former slave in South Carolina during the period of reconstruction following the civil war. One of his male line descendants, Charles Savage, aka Chuck, had his yDNA tested and found that he was a close match to men named Ferguson in the project's R- Z16328 subgroup aka R1b-Scots - Branch II. Two doors away from Lottie Savage in the 1870 census of Saluda, Edgefield county, SC is one Gideon Ferguson, a former overseer. So far as is known Gideon Ferguson never married and had no children. Gideon Ferguson had a brother Lewis E Ferguson who in 1870 also resided in Saluda, Edgefield county, SC. If either fathered Seymour Savage, the family tree would be as shown below. If Gideon Ferguson is the father of Seymour Savage then Chuck and Billy would be 3C (third cousins). If Lewis Ferguson fathered Seymour Savage then Chuck and Billy would be half 2C (half second cousins). The diagram below shows descendants of James Ferguson (1687-1741) that have atDNA tested.

Family Tree

The table below shows the total atDNA shared by representatives of each of the descendant lines in the above diagram. The large number of None is attributed to the fact that the probability of realizing a match between distant cousins is small. [Cousin statistics, ISOGG Wiki].

The table below is anchored off Billy. It shows the total shared atDNA compared to the average, minimum and maximum shared atDNA observed in the The Shared cM Project for the corresponding relationship. Billy and Chuck (aka *Chuck) share 169 cM which is in range for both a 3C and a half 2C, hence all that one can conclude is that either Lewis Ferguson or Gideon Ferguson could be the father of Seymour Savage1.

The relationship chart in The Shared cM Project indicates other relationships can share 169 cM but most are precluded in the present case because nobody in the genealogy fits with the MRCA associated with those relationships. For example, James H. Ferguson died before 02 Jun 1847, he could not have fathered Seymour Savage because he was dead before Seymour was born. Lewis I Ferguson could not have fathered Seymour because he was born after Seymour. Any first cousins of the brothers Gideon and Lewis Ferguson can be ruled out as the father of Seymour since then Chuck and Billy would be fourth cousins and the 169 shared cM is out of range for 4th cousins (0 - 127). The brothers had an uncle John Ferguson about whom the only thing known is that he died after 02 Jun 1847. If he fathered Seymour then Chuck and William would be third cousins once removed. This is possible though improbable given that only 12 of 1736 samples exceeded shared 168 cM in the The Shared cM Project.

Triangulation

Using GEDMATCH tools triangulated groups that include both Chuck and Billy have been found. The groups contain other aliases but how they connect is unknown.

Mourning Ferguson

Here is a triangulated group involving T953936 a descendant of William Jackson Collins (1806-1882) the eldest son of Mourning Ferguson and Thomas Collins. Based on an 1850 census record for Thomas and M Collins living in Chester, SC, Mourning Ferguson was born about 1785 in SC. How Mourning Ferguson is related to the Ferguson in the above family tree is unknown. That census record appears to be the only documentation naming the wife of Thomas Collins and even so only her initial is provided.

Mourning Ferguson

Mourning Ferguson is said by some to be the of daughter of William Yarborough Ferguson (1774-1846) and Anna Robinson (1793-1850). This cannot be so for she would have had to have been born at least 10 years after her mother making her too young to have had a son born in 1806. J. Collins (Chester County Message Board, 03 Oct 2004) says she is the daughter of John Ferguson and that she lived 1781-1854.

Regina Holler Perry (Chester County Message Board, 27 Oct 2011) speaks of a Collins bible naming her parents as Elizabeth Finley and Adams Ferguson. The will of Adams Ferguson written in Jan 1820 names daughters: Pricilla Edwards, Agnes Stroud, Anney Junkin and Betsey Lee, there is no mention of Mourning. He may have not mentioned all his daughters for he apparently did not mention all his sons, just the six oldest including William Yarborough Ferguson (1774-1846).

Some public trees say Mourning is the daughter of John Ferguson Jr. and wife Becky whose will was proved 29 Jan 1822 in Chester County, SC. That cannot be correct either since.the will indicates that his daughter Mourning has yet to marry or attain the of age 21, she would have been too young or unmarried when son William Jackson Collins was born in 1806.

Big Y

Chuck and FTDNA Kit redacted are a match at R-BY23079. They are not known to be related and differ at the STR DYS448 which seems to sperate one small group of Ferguson from the remainder in the common subgroup to which they belong. At this point there are no subclades identified within the R- Z16328 Ferguson
