Looking for marriage Michael McGovern Ann convey

[annclare]

I'm helping an English  friend get information on her Irish relatives. Information we have is Ann Convey b 1898 Cornaculla Fermanagh
Parents Thomas Convey/Conway Mary McManus-
 married Michael Mc Govern b.c. 1886 in Glangevlin Cavan and what is probably their 1st child born 1921 (have birth record) Mary Anne in Cornacully. Other children born between 1922 and 1931 in Fermanagh and then last 3 born in Cavan and have details of these.I have been unable to get marriage record to get Michael's father's name and try and get  information on the McGovern family.
Also looking for marriage of Thomas Convey and Mary McManus c. 1883
Would welcome any suggestions.

Thanks Dathai
I should have been clearer - I have got ann's birth record. The marriage you highlighted between Michael Mcgovern and Ann McManus - I don't think the names were mixed up as the townland Ann was living in at marriage was Cornacully and her father was Thomas. I think I'll have to accept that there is no record of civil marriage. Went into Werburgh St yesterday and checked marriages 1916-1921 but nothing found. Thanks for help.

PS Am still looking for marriage for ann's parents Thomas Convey/Conway and Mary McManus. I have records for Ann's siblings as shown in Census 1901 http://www.census.nationalarchives.ie/pages/1901/Fermanagh/Lattoon/Cornacully/1360651/
http://www.census.nationalarchives.ie/pages/1911/Fermanagh/Lattone/Cornacully/512430/
and 1911 

Oops just realised posted wrong surname for ann's mother and Dathai that's what you were pointing out - of course it should be McGowan A large Craft moment!!

IF they were RC you can check to see if Registers cover the dates you need.

It seems 1883 is too late for the parish records online.
