He had a relationship with Elizabeth KNOX.
John Welsh (1568/9-1622) was a Scottish Presbyterian leader.
Welsh was born in Dumfriesshire and, after a wayward youth, attended the University of Edinburgh and obtained his MA in 1588. He became a minister in Selkirk, and prior to 1596 and leaving Selkirk, married Elizabeth, a daughter of John Knox.
Welsh later ministered at Kirkcudbright and at Ayr, where he spent five years and with which his name was later associated. His preaching resulted in his imprisonment by order of King James VI of Scotland. In 1606 he was exiled to France, where he continued his activities.
Family
John Welsh and his wife Elizabeth Knox had four sons and two daughters. Their son Josias Welsh was minister at Templepatrick, and father of the Covenanter leader John Welsh of Irongray. The Welsh family has been of interest to genealogists tracing the descendants of John Knox
