Campbells - McNellis families from Donegal Ireland

Hello,

I am working on my family tree, and I am hoping for a bit of help. I am in a bit a of a rabbit hole let me try and to explain how I found myself in this situation.

My Great grandmother Margaret McNellis married Bernard Partridge in 1867 in Brown County Perry township Ohio.

From her death information from New St Joes cemetery in Hamilton Ohio( attached) it states her parents are James and Margaret Campbell.

Bernard parents Patrick Partridge and Helen McCormick are both buried at Saint Angela Merici Roman Catholic cemetery.

While doing research I found that there is a group of Campbells buried there as well. Especially a James Campbell b1774-d1850. Native of Donegal Ireland.

When I looked at the 1850 census, I noticed that my grandparents were living next to the Campbells.

Census #1

Line 23 Henry Campbell b 1802

Line32 Robert b 1806

Line 33 John b 1808

Line 39 Cornelius McNellis and Anna Campbell McNellis ( Margarets parents my GG Grandparents)

Census # 2

Line 3 James b 1816

Line 24 Hugh b 1823

Located in St Angela are the families of James, Hugh, John, and Robert. I have not located Henry or the others listed with him on the 1850 census.

 In researching the above I came across a book: The History of brown County by Josiah Morrow published by Chicago W.H Beers & co.

In that publication , which I have attached are articles on Cornelius McNelius

( my ggg grandfather)

 John Campbell (who is John Campbell line  33 on 1850 census)

And below him is James B Campbell who is the son of James Campbell

Line 3 of census #2

In the paragraph about Cornelius it states he was born on County Donegal Ireland in Dec 1819 marred Ann daughter of James and Margaret Camel ( I believe it was shorten for Campbell)   It states that my grand mother Margaret was born in Ireland and he came to America in about 1847 and settled on the farm in Ohio and was a member of the Catholic Church.

John’s article states he was the son of James and Margaret Campbell and was born in Donegal Ireland that he came to America in 1837 and went to Penn. With his brother James then to Ky for a bit. He went back to Ireland in 1841 to marry Hannah Boyle ( who is buried in St Angela with John and their children) in 1843 he returned to settle in the township on the land his brother James bought for him while in Ireland. The family are all members of the Catholic Church

James information confirms he is the son of James, John brother, and his wife Margaret Call born in Perry township in 1858. He is a member of the Catholic Church

From all of this gathered information I believe that the Campbells are all related and that my grandmother Ann was a part of this family and lived near each other in Ireland and possibility came over together . I also suspect the James b 1774 native of Donegal Ireland buried at St Angela is her father and the father of James, John, Robert, Henry, Hugh, and my Ann. I am seeking information to put it all together.

I was hoping that your society would have any information about these families.  I am on several web sites actively searching for records , Family search , Ancestry ect.

I appreciate any information, guidance you can provide me.

Thank you.
