Hi, Im still trying to research this family.
My 2nd G grandmother was Minnie Mussen born in Dromore to Rachel Mussen (before she married Moses Brown) Minnie is listed as UNKNOWN MUSSEN on Irish gen. her father is unknown, when she married she did not list a father. I dont believe it was Moses Brown who her mother later married.
Minnie married Matthew Douglas.
Her mum Rachel my 3rd G grandmother was born to Blaney Mussen (I can see he was mentioned here earlier)
I believe he married Charlotte Cunningham ( a charlotte mussen is listed on her death cert as widow of Blaney Mussen and her daughter Rachel also signs it)
Someone suggested Blaneys father as Phillip Mussen (of dromore) son of James Mussen and his mother Jane Logan. However I cannot find any suggestion Jane and Phillip had a son called Blaney, only that Phillip comes from 'Balleny' and my grandmother suggested Blaney was named after a place.
