Mary 1875
Ellen 1877
Sarah 1879
Elizabeth 1880
Owen 1883
William 1885
The above births are all registered Civil Parish of Buncranna, parents John McDaid, Mary McKinney
The record for Patrick comes from the Roman Catholic baptism also Buncranna, same parents
I don't have access to full records these are from indexed and advanced searches on a couple of different databases, some of the births from the 1870's are available on the family search site
https://www.familysearch.org/Use advanced search and in put parents names, John McDaid, Mary McKinney, (you'll see there is yet another son William McDaid born 1874)
As for the children not included am not sure, Sarah isn't on Census but may have died or been living elsewhere, don't see a birth record for Cassie, wondering was Sarah also known as Cassie, (birth dates close.)
Rose is from second marriage as is John, think all other children are from first marriage.
Also the grandchild is daughter Mary's son I think, child Edward McLaughlin baptised 1895 Buncranna RC Church father John McLauglin, mother Mary McDaid
