It's been fun
Luckily Andrew Lehan / Lehane / Levison does state in one Census County Mayo and his wife also, a later Census his Wife also states Westport - and yes there's a Westport in County Mayo so I think that's correct - Also almost positive they are Irish Catholic not found any marriages in a Parish Church even though some English Catholics did marry in them.
Just had a look for a Peter Ward marriage to Bridget only found one ESNE in 1853 Ormskirk not to happy with it, but made a note can't find the family Peter / Bridget with any certainty after The couple in Northumberland are a slim possibility (could have been counted twice in 1861) but again not with any certainty Also found one back in Ireland in 1911 - at this point no Certainties
Andrew Tarr yes it is a little challenging, I have no idea which 'Surname' to try.
I mentioned that I couldn't find a Catherine Lehane - I actually have found one - but its LOGAN and CathArine - think the Maiden name is O'ROUKE both not too far from Lehan and Horen/ Haren / Horan.
Because of EVERY Census / Birth Registration / Marriage (Leighen) being different then I am beginning to believe there might have been some trouble back home
They only constant seems to be when the surname changes to Levison - Heywood found me another family (I had seen them) that also changed their name from Lehan to Levison
