Index of Names in Irish Annals: Mac Goisdelb / Mac Goisdealbh

by Mari Elspeth nic Bryan (Kathleen M. O'Brien)

Family Name: Mac Goisdelb / Mac Goisdealbh

Background:

Spellings:

What we know as a set of Irish Annals are manuscripts that were each compiled during a particular time period, usually using older material as sources. For example, when the Annals of the Four Masters were written from 1632 to 1636, they covered events that occurred centuries and millenia before (including legendary history). So, when an entry in this set of annals refers to a person who lived in the year 738, the spelling used for that person's name is very likely not using the spelling that would have been used in 738.

Standard forms of this name (based on spelling systems of different periods) would be:

Early Modern Irish Gaelic (c1200-c1700) nominative form:	Mac Goisdelb
Early Modern Irish Gaelic (c1200-c1700) genitive form:	Mac Goisdealbh

Frequency & Dates:

Number of people found in the annals with this name: 44

Found in Years: 1193, 1194, 1195, 1200, 1201, 1211, 1212, 1213, 1214, 1225, 1236, 1245, 1247, 1253, 1256, 1259, 1263, 1266, 1282, 1285, 1286, 1287, 1291, 1312, 1217, 1325, 1327, 1328, 1330, 1333, 1337, 1340, 1343, 1346, 1366, 1383, 1416, 1428, 1437, 1438, 1439, 1461, 1464, 1467, 1468, 1487, 1493, 1496, 1536, 1545, 1547, 1549, 1551, 1555, 1557, 1560, 1561, 1581, 1582, 1586, 11588, 1589

Research Notes:

FM (vol. 3, pp. 98-99, footnote "k") states:

The Sons of Osdealv, i. e. the Mac Costelloes. –- According to the Annals of Kilronan, the island of Inish Cothrann was plundered this year by Gilbert Mac Gosdealv, and his English followers, and the sons of Gilchdreest Mac Carroon, vis., Gilla Croichefraich and Auliffe, who had the tribe of Muintir Maeltsinna with them. According to the Dublin copy of the Annals of Innisfallen, it was plundered by Gilbert de Nangle; and this is correct, for De Nangle was the original name of the Costelloes.

Woulfe (p. 397 s.n. Mac Oisdealb., Mac Oisdealb.aig.) states:

'son of Oisdealb.' (Os-shaped, shaped like the god Os); a patronymic surname assumed by the family of Nangle. It is the earliest Anglo-Irish Mac-surname recorded in the Annals (A.D. 1193).

Raw Data

In the table below, I have separated individuals with a blank line. That is, when there are multiple entries in the annals that refer to a single person, those entries are grouped together.

Within the list of entries refering to a single person, I have sorted the entries primarily by orthography when it is obvious that what I am seeing is the same entry showing up in multiple annals. The entries that tend to use older spellings are listed first.

Special factors which may affect name usage are marked in the context column.

AN indicates a member of an Anglo-Norman family

N indicates a Norseman

R indicates a person holding a religious office

S indicates a person from Scotland

NOTE: The Annals referenced below under the code letters A, B, C, E, & F tend to use later spellings than the other Annals. In some cases, the spellings listed in these Annals may not be appropriate for the year referenced in the Annal entry.

In some Gaelic scripts, there is a character that looks approximately like a lowercase f, but without the crossbar. This character (represented by an underscored , e, in the entries below) sometimes represents e and sometimes ea depending upon the context of the text.
