Y chromosome results for descendants of the earliest Roberts family in the Bahamas indicate that their direct paternal line is from southern Ireland and they likely descend from the Eoganachts whose ancestor was Olioll Olum, 3rd century King of Munster. The results also indicate ties with some Scottish Clans. The following are some of the closest matches with the Roberts participants.

The names in parentheses (e.g. ROBERT2) refer to the participants in the relationship chart at See

A descendant of Henry Roberts (ROBER2) matches 21 out of 25 markers with another participant with the surname of McCarty and 20 out of 25 match with a McCarthy. McCarty is a spelling variation of McCarthy. McCarthy is one of the major Gaelic families in Munster, a provence in southern Ireland. See Their ancestral home is McCarthy MOR CASTLE situated on the eastern shore of Loch Lien. In early times this district was known as Eoghanacht Loch Lein. The families, who ruled there, were descended from a common ancestor, Eoghan or Owen. See The McCarthy name from the earliest times has been associated with south Munster or Desmond. The third century King of Munster, Oilioll Olum, had two sons Eoghan and Cormac Cas. At his death North Munster (Thomond) was inherited by the latter (whence the Dalcassians), and South Munster (Desmond) by Eoghan. The families that descended from this Eoghan were known, before the introduction of surnames, as the Eoghanacht, and the surnames MacCarthy (in Irish Mac Cárthaigh) is derived from Cárthach, lord of the Eoghanacht. See

The Henry Roberts descendant also matches 22 out of 25 markers with another participant with the surname of Hinds. This is a spelling variation of the surname Hynes. The Hynes family is belived to descend from Eoghan (Owen) Mór, father of King Olioll Olum of Munster. The Hynes sept was forced west from Tipperary to Cork before 1300, becoming prominent by this date and very powerful after 1400. See

The Henry Roberts descendant is also matches 22 out of 25 markers with another participant with the Owen surname. Relatively close matches with the McCarthy and Hines surnames suggest that both the Roberts and Owen families may be direct paternal line descendants of Eoghan.

A descendant of John Roberts (Rober1) is a 20/25 match with an Donahue (DONAHU). The O'Donahues descend from Cas, son of Corc, son of Lugaid, son of Oilill Flann Beag (ancestor of all the Eoghacbhe), son of Fiacha Muilleathan, son of Eoghan Mor son of Oilill Olum See

The John Roberts descendant is also a 21/25 match with a Meagher. The family of O'Meagher, (the Cinel Meachair) are descended from Fionnchada, son of Connla, son of Cian, second son of Oiliol Olum, King of Munster in the third century. See

The John Roberts descendant is also a 23/25 and 22/25 match with a cluster of Daltons (DALTO1 & DALTO2). Dalton surname is identified as having historic or numeric importance County Waterford in the province of Munster. See Dalton is known to be a spelling variation of Daton and this family was prominent in County Kilkenny in the province of Leinster which boarders County Waterford. See and The Dalton family is also associated with Rathconrath Barony in County Westmeath in the province of Leinster.

Henry Roberts is also a 20/25 match with a Butler.  During the 13th century various Anglo-Norman adventurers succeeded in establishing themselves in Ireland, either by assisting or suppressing native clans.  The Le Botiller, or Butler family, acquired power in West Munster.  It is probable that the ancestor of this (Butler) participant adopted the surname of his overlord.  See

The names in parentheses (e.g. ROBERT2) refer to the participants in the relationship chart at See

The marriage of Olioll Olum and Sabina produced three sons. They were: Cian - whose descent were known as Clan Cian, and consisted of the Kingdom of Ely O'Carroll and Oremonde. Cormac Cas - whose descent was known as the Dalcassians which possessed the kingdom of Thomond, alternately the Kingdom of Munster. Owen Mor II - whose descent
became known as the Eugenians (or Eoganachts) and possessed the Kingdom of Demond, alternately the Kingdom of Munster, The seat for the Kingdom of Munster was at Castle Caiseal (Cashel). Corc, King of Munster, who was the great grandson of Olioll Olum through Owen Mor II went to Scotland and married Mong-Fionn, daughter of Feredach
Fionn, called Fionn Cormac, king of the Picts (Scottish). His descent which remained in Scotland were to become the Stewards of Lennox, of
whom the Stewart Kings of Scotland and England descend. See The Earls of Lennox also
granted lands and were associated with Clan Buchanan.  See

The descendant of Henry Roberts (ROBER2) also matches 21 and 20 out of 25 markers with Stewart participants (STEWA1,2&3). He is also matches 23 and 20 out of 25 markers with a cluster of Buchanans (BUCHA1 and BUCHA2). The Henry Roberts descendant and a descendant of John Frederick Roberts (ROBER3) are also match 21 out of 25
markers with a Reid. Both Reid and Roberts are surnames associated with Clan Donnachaidh See Clan Donnachaidh were neighbors of Clan Stewart in Atholl and served in Clan Stewart's Atholl Brigade See

This Roberts cluster also has close matches with the MacDonald and Cowan surnames of Clan MacDonald. This relationship is unexplained.
