Minchin/King Family

Hi there, 

I'm looking for any Minchin, Church of Ireland, descendants from County Roscommon.

I'm researching my King family tree. My three times great grandad was called William King. He was from Emlaghfad. His wife, my three times, great grandma was called Letitia and born in Ireland.

I know that their children were born in Ballymote; from looking through the England census. I know there was a minimum of six children however i've only located records for three of them. 

Letita came to England sometime after 1855, as a widow, with at least four of their children; and William's unmarried sister, Mary, following William's death somewhere between 1844 and 1855. 

Letitia's age year changed between 1861 and 1871 England Census; 1808 and 1810 respectively. Mary King, William's sister was born in 1790.

I have searched Roots Ireland and believe I have found William born 1792. There is also a record with matching parents, Thomas and Honora King, for his sister Mary King born 1790. 

The only marriage I can find for a William King around that period is in 1836 to a Letitia Minchin in Eastersnow church. I believe their eldest child, Thomas, was born in 1837 so it would tie in. Eastersnow church, if my information is correct, is the next Church of Ireland from Emlaghfad.

I have found a mention of her on another site that says Letitia is 21 when she married. I have not found the record that can confirm this so that I can at least rule her out of my search.

Any help would be great. 

Thank you,

Vicky :)
