I have the marriage cerificate of John (age 20) and Winefred Larvan (age 19)
John was a Mason's Labourer, residence Batley, Father's name James Larvan. Joiner
Winefred, no occupation, residence Batley, Father's name Patrick Larvan, Farmer
Both fathers appear to be alive at the time of the marriage
Witnesses are: Catherine Lundy and Luke Larten (diificult to read - Perhaps Luke's name was Lawton)
If Lavin becomes Larvan, I can see Lawton becoming Larten!!
Perhaps the only ongoing clues are the father's occupations??
Or maybe a marriage between Cathering and Luke?
