Lewington / Dublin

[Michelinamay]

Good evening I am
Looking for a birth of William Lewington 1832 possibly Dublin Died 1900 in  Lymington England Parents are Catherine Neagle and John Lewington and a marriage
William married Mary Ann Nichols in Northamptonshire?  1863/4
Then I’m hoping it will fall into place if they are the parents of James Lewington 1864 can’t find a birth record in Ireland or England
Could anyone please push me in the right direction
I have looked on Find-my-past,  Ancestry, and and the Irish records but have got nowhere
Thank you for any help
