I have collected information on McMeekans (with lots of different spellings, including McMahon) in the area, but can't link yours with my family, as I can't see the early Presbyterian church records for the 1st Newtownards.
I hope to have another try at asking the minister if I can look at them. I will let you know if I find a connection.
I looked in the Graveyard Inscription book for Bangor, and saw what is probably your Hugh.
You might have this already.
Erected by Hugh McMechan of Bangor, in memory of his daughter Margaret McMechan who died Octr. 13th 1828 aged 3 years. Also the remains of his son Hugh McMechan died 27th Decr. 1834 aged 12 days. Also the remains of his wife Margaret McMechan alias Aiken died 28th August 1840 aged 39 years. Also the said Hugh McMechan who died 23rd Decr. 1840 aged 48 years.
My grandmother was Maggie Jones. Her mother was Maggie (McMeekan) Jones.
My grandfather was Joseph Mooney. The Jones Mooney and McMeekan families were all from Church St. Newtownards. And probably knew each other for a long time.
My great grandfather John Mooney was a stone mason, and so were a lot of the McMeekans.
One of Charles McMeekan's daughters was born in Ayr, around 1876, although they didn't stay there
Charles did not seem to be at home much.
His wife's family had a house at 14 North St. Newtownards, where the couple lived, but Charles was not in the 1901 census, although Margaret was not said to be a widow.
I am researching a family for someone in America, but have just found living relatives for her in
I am in the process of sorting my notes to send off to them.
When I finish this I will concentrate on my own family, and look for more McMeekan births etc.
I will let you know of any progress.
