Hi Eric,
That couple you mentioned - Nich Keanish & Margt with son Nicholas bapt 10 Feb 1733 Maughold - were I think Nicholas Kinnish & Margt CALOW who married in Braddan on 2 July 1728. - So yet another Kinnish family with Braddan connections in the early 1700s.
The Maughold parish register has bapts:
William son of Nicholas Kynish & Margaret bapt Parish Church 21 May 1729
John son of Nicholas Kennish & Margaret bapt Parish Church 21 Mar 1730/31
Nicholas son of Nicholas Keanish & Margaret bapt Parish Church 10 Feb 1733/34.
According to Constance Radcliffe in her book “History of Kirk Maughold” the name Kennish/ Ceanish “is always associated with the Corony, both the Quarterland and the area around the bridge, but there were originally two Kennish families, one on the Corony and the other at Ballagorry. A William Kennish (d.1742) who married Alice Creer (d.1745) bought half the Corony quarterland .... Another William Kennish who died in 1714.... in 1708 bought part of Ballagorry Beg (the part below the road)”.
She says the two William Kennishes must both have been born between 1660 and 1670, “and, if not brothers, were probably first cousins, as the rather unusual names of Nicholas and Peter are found several times among the descendants of each, along with Ewan and Thomas, and of course William, John, and Robert.
The first William of Ballagorry Beg had one son, also William (1701-1771) who had five sons and one daughter. The eldest son Nicholas (1721-1744), was drowned on the English coast.... His father William, on his death, divided his lands between his eldest surviving son John (1723-1786) and youngest son Peter (1755-1815), with a small portion to his fourth son Thomas (b.1731).... William’s other two sons, James, a joiner (1727-1800) and Thomas, established themselves near to the Corony Bridge, James buying part of the Corony quarterland east of the main road in 1787, and Thomas buying part of Cardle Vooar in 1760 ....
William Kennish the poet was the youngest son of Thomas junior, and was born in a cottage by the stream, where the bungalow ‘Ainchea’ now stands”.
“The Corony quarterland lies on the south side of the river and bridge, and was divided into two from the earliest times, the division following approximately the line of the main road. This road must also have been in existence from very early times, leading, as it does, to and from the most convenient river crossing. The half of the quarterland which became the Kennish half was on the west side of the road, around the present Corony farm-house... By his marriage to Alice Creer (d.1745), William Kennish had two sons, Nicholas (1698-1736), the heir, who predeceased his father, and William (1712-1792), who bought part of Crowcreen. The two sons of this William's eldest son William split the Crowcreen lands between them in the early nineteenth century, one branch retaining land at the top of the hill, still in the possession of the family, and the other remaining at the Lhag, at the foot of the hill....
In the main line of the half-quarterland itself, Nicholas was succeeded by three Williams, the last of them being still in occupation in 1861".
"Nicholas (1698-1736), the heir..." perhaps the one who married Margaret Callow?
