Thanks to everyone for your info.
Seems I am on the right track..
Marriage information was useful. I believe Edward (known to me as Ned) was married twice.
To Sarah Harte and to Sarah Hull (unsure of this second name) there were no children from that marriage.
The children from marriage to Sarah Harte is correct.
Would be very interested in any knowledge of Edward’s father Archibald or his mother .
Regards
Edward McMaster's parents were Archibald McMaster (son of Arthur) & Elizabeth Arthur. (daughter of John Arthur & Elizabeth Moore). Elizabeth Arthur's parents & all of her siblings went to Canada and there's a large connection there yet.
Archibald McMaster & Elizabeth Arthur had 11 children: William, Sarah Margaret, Archibald, Mary Eliza, Jane, Thomas, John, Hannah, Samuel, Edmund, Sarah Margaret. The first Sarah Margaret was baptised by her grandfather John Arthur & she went to Canada with the Arthurs. Son Samuel later joined the family in Ontario. There are still quite a few of their descendants in the Aghadowey area.
