Searching for Steenson, Stevenson and Hughes

Hello Col,  I guess you are not seeing my message in full as I gave details of people (by mistake, I sent the first one blank as it was the first time I used the site).  I am copying and pasting the message again, here..............help appreciated.  Thanks

I am visiting Northern Ireland for the first time next month.  I want to visit the area of my ancestors, so please, does anyone have the following in their trees? The spelling of Steenson and Stevenson seems interchangeable. I would love to hear from you if you link up with the following:

• William Steenson born 1854 in Ballybrawley – father Joseph
• Joseph Steenson born ?, brother of above
• Margaret Hughes born 1844 married to William (above) at Eglish Parish Church in 1874
• Mary M Steenson born 1885 – Ballybrolly
• Margaret Ann Stevenson (my grandmother) born in 1887 Ballybrawley
• Ann Hughes born 1809 in Fermanagh (maybe aunt of Margaret Hughes)

Does Eglish Parish Church of Ireland still exist?  Where is Ballybrolly and Ballybrawley; are they the same place?  I cannot find villages with the names of Eglish, Ballybrolly and Ballybrawley.  Any help would be appreciated as I do not know much about this family except they came to London by 1881.
