Sorry for the delay but can provide a bit more information on Savage connection (checked my files but don’t have much more about McShanes than what Elwyn has found already). To clear up some confusion from previous posts-
Milltown is in Culcrow, just as Meathpark is actually in the townland of Ballybrittain.
Savages were a mixture of Presbyterian & Reformed Presbyterian. Some attending Ballylaggan R.P. Church and other attending Aghadowey Presbyterian Church, Crossgar Presbyterian Church, etc. There are 2 Savage headstones in Ballylaggan but unfortunately few others.
Ballylaggan marriages would have taken place in the Registry Office but often the couple also had a religious service in the church. In these cases a newspaper announcement would have usually listed the place of ceremony as the church. Several Savages were Reformed ministers. Ballylaggan has excellent records (baptisms start late 1700s but early ones only give date of baptism, name of child & father’s name (residence & mother not recorded)- not sure when mother’s names became included but after 1860s at least- these records are not online.
Samuel Savage (d.1884) was baptised by the minister of Crossgar Presbyterian Church 17 Apr.1841. His parents were Samuel & Jane (possibly Jamieson- the Savages lived next to Jamiesons at Gills and the surname was used as a middle name for several Savage children). Isabella Boyd Savage named after Isabella Boyd wife of Paul Orr (think there was a family connection but can’t remember it exactly at the moment). Charles Lynd Savage’s middle name came from the Lynds of Knockaduff but there’s no known family connection. The Ironmonger’s agent’s surname was Craig so that might be where Sarah’s name came from.
"I found a gravestone for a Savage of Culcrow in Ballylagan Reformed Presbyterian church graveyard: In loving memory / of / Samuel Savage / Culcrow / died 21st December 1883 / aged 48 years / his daughter / Sarah Craig / died 2nd December 1908 / aged 37 years / his son Hugh / died 8th June 1903 / aged 37 years / Also Eliza / daughter of the above / Samuel Savage / died 24th August 1928 / aged 82 years."
The above transcription is full of errors. The stone actually reads: In loving memory of Samuel Savage, Culcrow died 21st December 1884 aged 48 years. His daughter Sarah Craig died 2nd December 1902 aged 17 years his son Hugh died 27th June 1903 aged 37 years. Also Eliza wife of the above Samuel Savage died 24th August 1928 aged 82 years.
Jamiesons of Gills were also buried at Ballylaggan & family headstone says Nancy, daughter of William & Isabella, was the first person interred in the graveyard (1826).
Hope this is some help.
