Hi, this is my first post so apologies for any errors/issues.
The Edward ORPEN that you mentioned, the individual married to Maria Crumpe (reportedly his cousin) had the children:
- Richard
- Samuel
- Daniel
- John Wood
- Grace
- Mary
- Anne
- Lucinda
This Edward Orpen is son of Richard of Ardtully Orpen, son of (another) Richard of Ardtully Orpen, son of (yet another) Richard of Ardtully Orpen, son of Richard Orpen of the White House who is married to Isabella Palmer.
I have found this information in "A Genealogical and Heraldic History of the Landed Gentry of Great Britain & Ireland, Volume 2" by Bernard Burke, which if you search in Google you will locate an online copy of, I am referring to just at the top of page 1031.
The Orpen - Moriarty line is a different line of the Orpen family with a different Edward Orpen (I am assembling my own version of the family links based on this source and a second source, so far I have located 6(!) individual Edward Orpen's). Major Edward Orpen of Killowen married to Elanor Connor, and had many children including Anne.
Lieutenant Redmond Moriarty and Merion Marshall Moriarty M.D. married Dorcas Orpen and Anne Orpen respectively, both of whom are sons of Admiral Sylverius Moriarty and daughters of Edward Orpen respecitvly (this is detailed in the Limerick Advertiser from 1816) [Anne married Merion, not Redmond].
Both Merion and Anne are buried in St Thomas Rest Park, Crows Nest, Sydney, Australia. I visited the location, and (my) photograph of the grave can be seen here: wikidata.org/wiki/Q104831632 and a photograph of the plaque attached here: wikidata.org/wiki/Q104828293. Note that the Sylverius Moriarty mentioned on the plaque is not the aforementioned Admiral Moriarty, but if I recall correctly, one of the children of Merion & Anne.
Thank you for all the information in this thread. Please alert me to any errors I may have made as the Moriarty - Orpen line is one to which I am directly descended.
