Hi Liscoole
Well this is most interesting. I too stumbled across the Markethill Presbyterian church records online only yesterday. When I saw "Thomas West McCullough" son of Alexander McCullough my ears pricked up because my 3G GP's according to the family are "Alexander McCullagh" & "Sarah West".
Now, my 2G GF "Alexander McCullagh" (born bet 1830-1831) was married to "Anne/Anna Munro". They emigrated to Australia in 1863. They already had 5 children when they left (John, David, Maria, Samuel, Joseph, but not sure if John & Samuel came too or not). In Australia they had 2 more, Elizabeth (1867) & Thomas (1869). Maria is my great grandmother & in Australia at least, they were McCullagh.
So this is where it starts to conflict, because this also appears to be your Alexander (31/8/1830), BUT your Jane was born in 1868, and baptised in Markethill, which my info would say they left behind in 1863! Also my Alexander McCullagh (b1830-1831) was married to Anne/Anna Munro, not Elizabeth Patterson. So whilst your G GM Jane and my G GM Maria would appear to be sisters if you forget about the fact we have different mothers married to possibly the same Alexander! But there has to be a very close link somewhere.
Whilst I don't have any records to back it up, I assume my link to Sarah West & Alexander McCullagh has been verified by a family cousin or such who had access to the death certificates or some such. We have always been told it to be so, and this was long before the internet gave us access to so much info!!!
Curious and curiouser. Look fw to hearing back!
Regards, Fiona (ps, where do you hail from Liscoole)?
I also have about 10 variations on the spelling of the location. Deraharra, Derahara, Derrahara, Denahorra, Denaharra, Dennyhara, Dinnahara, Dinnahorra, Derrihora, & perhaps even Derrydorragh!
