Hi John
OK I can see this other persons tree on ancestry.
Firstly I must state that I am NOT a professional genealogist.
Given that this other person hired a PROFESSIONAL GENEALOGIST I would usually defer to those with credentials BUT there is one vital issue that I would like your family to note.
The tree states, and I can only presume that they were given this information by the hired genealogist, that Francis was from Dundrum.
HUM
Dundrum is NOT in Wicklow - where ALL his census records state that he was from.
ALSO
Did you see the prison record that I gave you guys whereby Francis states that he was from Delgany in Wicklow.
The tree had given Francis ALL sorts of siblings based on a Dundrum family but I REALLY don't think this is the correct scenario.
ALSO
The tree states that there was a marriage for a Francis McDermott to a Teresa McNamara in 1868 YET there is NOTHING to back this up attached to the tree.
There is a child stated as being Francis McDermott Junior born 1868 to this couple and this is where the Australian Contingency enter the frame.
This is Francis Junior

There are a few scenarios ~
We know that Jane Dawson is 100% correct and is the mother of John McDermott, and this is of course the most important part of the tree as it's where you and Maureen come into the frame.
We know that Francis was a widower when he married Jane.
BUT he could have been a widower TWICE over.
He could have been married to Teresa McNamara, had a child called Francis and then Teresa passed away.
He could then have gone on to marry Mary Clements, had a daughter called Maria, and then Mary died.
He then, either way, went on to marry Jane Dawson.
There could also have been illegitimacy.
We know that he was married and widowed prior to Jane BUT it could have just been ONE of these ladies, making either of these 2 children illegitimate.
It's SUCH a shame that for some reason Francis was not fond of getting his marriages and children's baptisms officially registered.
