A Sissie McClements was informant of her father's death - is Sissie a pet name for Sarah? 

This may be her (taken from Emerald Ancestors:
Record Type Civil Marriage
Date of Marriage 25 Dec 1925
Groom Name john MOFFATT
Bride Name sarah MCCLEMENTS
Church Macosquin Presbyterian Church
Parish Camus-juxta-Bann (Macosquin)
Civil District Coleraine
County Londonderry
This marriage is not at GRONI, even for 1926.  It would also be odd for Samuel McClements to have two of his children married on the same day in 1925, though, having said that, I think David's marriage was 23rd not 25th December, when you look closely at the cert.
