Do you have any known sibling names or any other leads?
I have checked Roscommon Roots for the early 19th century and found:
- NO baptismal records for a Charles McDermott (son of James & Catherine McDermott)*
- Marriage records for any James McDermott & Catherine X only survive from 1830.
*The only James & Catherine McDermott baptising children in the 1820s (around when Charles was born) were James McDermott & Catherine Beirne of Cloonybrennan, Elphin (m.1811). The Elphin parish records are fairly intact so I would expect to see a record for Charles turn up in that family. However, the gap between the child born in 1820 and the next in 1825 seems rather long (at that point a child would have been born every 2 years or so, not 5). While it is a possibility that Charles' baptismal record is simply missing, I have not seen any recurring instances of the name Charles in Cloonybrennan (i.e. that it belongs to any family tree here).
If we take the view that the priest may have recorded the father's or mother's name in error we find:
- Charles McDermott b. 19-Jun-1821 also 23-May-1840 (sons of Charles & Catherine McDermott CROGHAN);
- Charles McDermott b. 22-Apr-1822 RIP; 01-Jun-1823 RIP; 12-Apr-1838 (sons of James McDermott & Judith Regan LOUGHLYNN)
- Charles McDermott b. 24-Apr-1825 (son of Owen/Eugene McD & Catherine Maguire CROGHAN)
- Charles McDermott b. 12-Oct-1827 also 08-Sep-1861 (son of John McD & Catherine Burns BOYLE)
- Charles McDermott b. 17-Nov-1835 (son of John McD & Catherine Sheridan of Corracoggil LOUGHLYNN)
- Charles McDermott b. 08-Sep-1861 (son of Charles McD & Catherine Bruen BOYLE)
- Charles McDermott b.11-Oct-1900 (son of Charles McD & Catherine McGreevy BALLAGHADEREEN)
That is not to say there were no others, as not all parish registers survived.
