Please would tell us where you got the information about William and his brother John Donnan.
I started by looking at at
Ros Davies website first for her list of Donnan, Donnin, and Donnon and then to educate myself about the areas mentioned so far. Ros Davies tells us “Balliggan Balliggin in the civil parish of Inishargy 21; 62/65 4km SW of Ballywalteretc etc
Ros Davies has the map showing the civil parish of Inishargie and its townlands.
Ballygarvan Townland
Ballyobegan Townland
Fish Quarter Townland
Glastry Townland
Gransha Townland
Horse Island Townland
INISHARGY Parish and Townland
KIRCUBBIN Village and Townland
Mid island ? may be included
Nunsquarter Townland
Roddans Townland This is sometimes included under Ballyhalbert parish
Rowreagh Townland
Scady Rocks Townland information is scarce
Sheelahs Island Townland
South Sheelahs Island Townland [part of Sheelagh above]
An overview notes, the other adjoining northern parish of Greyabbey and the southern adjoining parishes of Ardkeen and Ballyhalbert., with the importance of the civil parish in finding further records, but also the key towns of Kircubbin in Inishargy and to the north Newtownards & Donaghadee ,and Portaferry to the south

Ros Davies ‘Donnan’ entries can be expanded for example on
www.familysearch.org I confined myself to see what was available for the surname in their Ireland Births and Baptisms, 1620-1881 and narrowed that down to PRESBYTERIAN Church records ,KIRCUBBIN,DOWN,IRELAND and found three males of the same first name having children

James Donnan christening: 14 February 1815 father: James Donnan
WILLIAM DONNAN Children

I stopped at this convenient point realizing one needs to exhaust the records which Ros Davies lists as Kircubbin Presbyterian Records available are baptisms 1778- 1826, marriages 1781-1845; North of Ireland FHS (
www.nifhs.org) has baptisms 1778-1921 & marriages 1781 -1920;
www.familysearch.org have baptisms 1778-1826 on batch #C700361; graveyard attached, gravestones UHF Vol 12 ; oldest stone 1800; email me Ros Davies for a gravestone look-up. Of course there are many more records on familysearch.org, but I am trying to cut corners at this stage so I moved to
Ulster Historical Foundation { also operates a membership association called the Ulster Historical and Genealogical Guild} website is
http://www.ancestryireland.com Some of their indexes are free. I deduced from their Donnan entries
Anthony Donnan b bef~1773
Children

So that’s as far as I can go.
