Hi Trish there is a snag... Alexander the dad born     
Alexander WYLLIE Married Janet CLARK, 17 Jan 1795, Neilson, Renfrew, 
Janet WYLLIE, 75 (1776), born 
Alexander Wylie, born 8/Oct/1826. Stewarton, Ayrshire,
Agnes Wylie, born 30/June/1829. Neilston, Renfrewshire,
Janet Wyllie, born 26/June/1831. Kilmarnock, Ayrshire,
Mary Wyllie, born 27/Oct/1837. Kilmarnock, Ayrshire.
Alexander WYLLIE
Scotland, Births and Baptisms, 1564-1950   
christening:   29 November 1795   NEILSTON, RENFREW, SCOTLAND
parents: Alexander Wyllie, Janet Clark
ROBERT Wylie Chr 09 March 1823, 
If Robert was first born then Alexander's Church  of Scotland record is wrong it says Alex 1st Agnes the 2nd.
 What do you think. It looks good but maybe Janet in this Alex was married to another  woman called JeanClark?
