He was active in the Kingdom of Strathclyde in the area of East Renfrewshire, where there were “Conval wells” in Barrhead and Thornliebank.
[2] He is believed to have founded churches at Inchinnan, Pollokshaws and Fereneze (near Barrhead).
[3] The Aberdeen Breviary records traditions that he was a disciple of Kentigern in Glasgow, but this may have originated from 12th century bishops seeking to bring the Inchinnan church under their jurisdiction.
[4] In the 12th century David I of Scotland gave the Knights Templar a church in Inchinnan dedicated to Saint Conval, it was replaced by 'Hallows Church' in 1900, then demolished in 1965 for the extensions of Abbotsinch airfield into Glasgow Airport.
[5] A stone, thought to be the base of an early Christian cross, is protected by cast iron enclosure near the bridge at Inchinnan, and is known as "St Conval's Chariot" which supposedly brought Saint Conval from Ireland to Inchinnan.
