Hello Betty.In the case of my Great,Grandpa being a "Chimney Sweep",and
being invited to a Wedding?Well,He should have got married Himself at least
9 months before his first child was born?
But he did'nt follow Form I'm Afraid! Because you see,He got Married to his
wife in 1890,which was 12 years After his Missus had the first
child.[Francis ELLIOTT,1878-1920]And then they had another 6 kids.The last
being born in "Wedding Year"of 1890.
But hey! He was just following his Parents.As they had a son Charles ELLIOTT
born in Swansea in 1850,then they have another 6 kids,and decide to get
married in Newport Register Office in 1867.
Moral being....Do not expect everyone to follow the norm!
 at least 9 months later, = "Kids".
