Hi Clive,

Maughold par reg entry has only William illegitimate son of "W Moore" & Mary Corteen bapt 24 Jan 1830.

1841 census:
3 11 43 pt of Tallooqueen Molly CORTEEN 35 Isle of Man

3 11 43 pt of Tallooqueen Mary MASLEY 15 Isle of Man

3 11 43 pt of Tallooqueen William MOORE 12 Isle of Man.

Mary dau of John Corteen & Ann Sheay bapt 23 Jul 1804. Private baptism.
Her brother Edward Corteen bapt 1807 Ramsey.

John Corteen & Ann Skeay married Maughold 6 Oct. 1803.

"Mary Masley" looks like Mary Ann illegitimate dau of Mary Corteen bapt 9 Jan 1825.

Maughold marriage:
9 Feb 1850
John KINRADE Full age Bachelor Shoemaker Kirk Andreas, [father] John Kinrade, Labourer
Mary Ann MASTYN Full age Spinster Thalloo Queen, [father] Joseph Mastyn, Labourer.

1861 census Maughold:
1 56 Church Road South West John KINRADE Head MAR 40 Iron Ore Miner Andreas

1 56 Church Road South West Mary Ann KINRADE Wife MAR 36 Maughold

1 56 Church Road South West John J KINRADE Son 7 Scholar Maughold

1 56 Church Road South West William H KINRADE Son 4 Scholar Maughold

1 56 Church Road South West Robert KINRADE Son 0 Maughold

1 56 Church Road South West Mary CORTEEN Mother in Law UNM 58 Assistant Maughold

Mary's father John Corteen could have been the son of John Corteen & Catherine Stole bapt Maughold 29 Jan 1764, or the son of Edward Corteen & Mary Kerruish bapt Ramsey 19 Nov.1769.

The Thallooqueen census address suggests the former.

John CORTEEN (Thallooqueen) was buried Dec 3 1815.
His will:
CORTEEN, John 1815 Mau A 86 0106240

Possibly Mary's burial: Mary CORTEEN aged 75, Cardle Voar, May 3 1878.
The 1871 census should give further info. about her?

However there is a problem with the MOORE son in this family.
The marriage you thought was his can't be right, because it has him as a minor:
30 Jul 1854:
William MOORE Minor Bachelor Labourer Ramsey William Moore, Tailor

Elizabeth MYLREA Full age Spinster Ramsey John Mylrea, Tailor.

This marriage looks like that of William the son of William Moore & Christian Fargher bapt 24 Aug 1834, and not your illegitimate William Corteen/Moore.

There is a William Moore of the right age living in Cumberland in 1881 with wife Frances and children.
