Hi,
I would hazard a guess, that Emily and Joseph weren't divorced, but you never know

On the marriage entry Joseph is down as 'bachelor' and they were married in Partick,on the 29 Dec 1899, the entries were made in 1900, if you would like a copy of the entry, send me a PM of your e mail address and I'll get it off to you.
Elizabeth Gillespie jnr was born illegitimately to Elizabeth on the 16 Sep 1897, wonder if she was Joseph's, if she was, why did they wait so long to marry?
Catherine Green Wigglesworth, (Green was Elizabeth's mother's maiden name), whom was on the 1901 died aged 4 in Partick.
It is going to be interesting to see what John manages to find out for you.
