Seeking descendants of Julia Connolly and Andrew Perry

I read a previous post from Anniep 20th January 2020 who appears to live in Australia.  I now can't find this.  It was enquiring about her husband's great grandfather  Andrew Perry who was married to Julia Connolly from Galway. They married in Glasgow in 1870. On reading this post I realised that these are also my great grandparents. The reply to the original post was a referral to a local volunteer that could be contacted by email.  My grandmother was Catherine Perry born 14th Jun 1872 died 1952 and my granfather was  Parick McDonald  b. 1872 in Gorbals Glasgow and died 1941. They were married 13th July 1894 in Hutchenson Glasgow.  I am the daughter of their son John McDonald b.10th May 1911 died1st Nov 1967. He married my mum 17th July 1943. I was brought up in Glasgow and now live in Bristol UK

I have done some research into my family history and have some information that could interest Anniep.  I think her husband and myself must be related in some way.  Happy to respond to any reply to this post.  Morag Andrews-McDoanld.
