Hello Joan, is this the John McNeil you are searching for in the 1841 Census ?

This is extracted from Brian Lawson’s census index, and needs to be checked on the original census entry,

1841 Census, Isle of Man, Douglas
1465/4 : 36 : 19
McNeil John 20
McNeil Mary 35 (could be a wrong transcription of Margt.)
McNeil John 6
McNeil William 4
McNeil James 2 (could this be Isaac as in 1851 census is aged 12 )(check the spelling on census)
McNeil Clara 10 months (could this be Cleve)

1851 Census, Isle of Man, Douglas
2525 : 375 : 64
McKneale John 44 (could be trying to match his wife’s age ? a real gentleman)
McKneale Margaret 44
McKneale John 16
McKneale Isaac 12
McKneale Thomas 11
McKneale Clare 10 (Cleve, born, 1840 ?)
McKneale Elizabeth 6

1851 Census, Isle of Man, Braddan
2525 : 461 : 16
McNeile William 14 (check where this William is born,age 4 in 1841, age 24 in 1861, ?)

hope this helps,
Averil
