I have the 1861 marriage record for William John Lynas and his wife's name is Mary ANN Boyd not Mary Jane Boyd. This is probably why none of the trees currently on Ancestry can verify the marriage of this man. I am a Lynas researcher also and have many Williams in my Lynas family name. Also my grandfather was a Robert Lynas 1865. Your tree comes up lot in my searches due to the many similarities in our trees. If you contact me at
b.care@sympatico.ca I will email the record to you.
