Sir Dennis Henry (b 7 March 1864) Draperstown - connection to Nancy Henry

[Cwellan CoDown]

Hi everyone

I have been researching my husbands family tree and have found the his ggg grandmother is Nancy Henry.

All I know about Nancy Henry is that on 7 March 1841 she married William Doogan in Ballinascreen parish church.

Now I know they are related to Sir Dennis Henry - see the link below

And in the 1911 census there is an Catherine Dougan  who is living with Mary G Henry - cousin, and Alicia Donaghy (nee Dougan) is also a cousin visitinf

And in 1901 she is living with 2 dougans also

Can anyone help me find the connection?

There is a Miss M Henry listed in the draperstown directory in 1910 - as a woolen draper, boot and shoe Merchant.
