I just turned this up on a web search about Donnans. My wife's grandmother was called Donnan. She came from a place called Ballycranbeg about 3 miles south of a village called Kircubbin in Co Down. (This makes her sound like a hick but in fact her father was a well off farmer and she attended Queens University in the 1890s and then the Sorbonne for a year). There are certainly Francis Donnans in Ballycranbeg = which is called a townland i.e. a place with a collection of buildings and farms which is not quite a village. There werer a number of Donnan farms in Ballycranbeg. I have just last week combed a transcript of the baptisms in Kircubbin Presbyterian Church. There was a Francis Donnan, father also Francis, baptised on 11 June 1829. The father was said to be from Ballywalter. This is on the other side of the Ards peninsula from Ballycranbeg but is only a few miles away. It is odd that there are no other Francies in the Kircubbin baptisms because there are definitely more in the area. Unfortunately in those days the church did not mange to note the poor mother's name. I guess they thought it was nothing to do with her. The Franci Donnans may of course have been Church of Ireland. We haven't looked in the Kircubbin C of I records so maybe there. We did record the Inishargy C of I. No Francis Donnans there. Maybe Glastry. I am sure you can get the films for these in the Mormons' Family History centres. The other names which might be relatent are Ardkeen, Ballyphillip and Portaferry, either C of I or Presbyterian. Sorry this is not very specific but it might give you a steer. I am pretty sure btw that the Francis Donnans in Ballycranbeg are related to my wifes family but can't make the connection because of the omission of the mothers' names in the baptisms.
