Connections between Ontario Lynns and Carolina Lynns?

Question

I am looking to connect my Lynn ancestors who emigrated from Antrim, Ireland to Frontenac and Leeds Counties in Ontario at the time of the potato famine with their Lynn relatives who settled in the Carolinas and/or possibly Virginia and Georgia: In family lore (copied from notes and letters- principally a letter to Addie Whitmarsh from Bertha Shillington, the information apparently came from Aunt Rebecca Lynn after her sister Aunt Alice Lynn’s death c.1940): “Because the times were hard, families broke up. Some of the Matchet’s as well as some of the Lynn’s came to North Carolina and Georgia. A number of William Robert Lynn’s uncles and their sons went to Carolina. Some fought in the Civil War. During the war, some were killed and the remainder scattered throughout the United States." My guess is the families must had correspondence either with each other or with family back in Ireland in order for this information to come down to me. Such letters if they existed, have been lost.

Can anyone help?

Answer 1

My great great grandmother was Liza Lynn. I have found relatives through DNA testing that are likely connected through Lynn based on shared DNA matches but I don't know how I am connected to them.  If you have done DNA testing, we can validate if we are related.

This is her profile:

This is what I know about her:

1. Liza Lynn left Ireland with her parents at age of nine, they were enroute to West Indies where her uncles owned plantations and who were in good financial circumstances. (c 1828)
2. Liza's father died of fever on the boat and she and her mother then returned home to Ireland. They came to Canada some time later and lived with her mother's twin sister would was married to Mr.Coulson. 
3. Elizabeth (Lynn) Linn was buried, at Coulson Hill Cemetery. 
4. Elizabeth (Lynn) Linn was born circa 1819, at Ireland(from 1871 census and McAfee book). She was the daughter of Matthew Linn and Martha Maclean??-Lynn-Quay. 
5. Elizabeth (Lynn) Linn married Robert McAfee, son of John McAfee and Martha McKay, after 1830. (but before 1840)
6. Elizabeth (Lynn) Linn died 13 Mar 1890, and McAfee book says she died at age 71 (Simcoe Co.).
