Hi there,
I notice that your message is from a few years ago, so I hope this will still get through to you. It seems we might have some of each others' jigsaw pieces! I have been looking into the history of my grandmothers and aunt's mother, who is Annie Lovat, and whose death was registered in 1918 by her daughter Mary McColgan. The existence of this daughter, or any other children was unknown to us until now. My gran was around 8 and my aunt around 4 when they were both orphaned by Annie's death - my aunt too young to remember, and my gran would never speak about the details, not even to my aunt. Both of their birth certificates may give some clues to why you have discovered that Hugh was married in 1909 as a widower, but Annie did not die until 1918.
My gran's birth certificate for 1909 states the mother as 'Annie Devoy or Lovatt' and in the details about the father states: 'Annie Devoy wife of Hugh Lovatt, labourer who she declares is not the father of the child and further that she has had no personal communication with him since they ceased to reside together about 4 years ago'. there is no father named.
My aunts birth certificate for 1912 gives the father as Patrick Kerrigan and under the details states 'Annie Devoy, wife of Hugh Lovatt, Chemical Works Labourer, who she declares is not the father of the child and further that she has had no personal contact with him since he left her seven years ago'
When Annie died, Patrick Kerrigan was unable to look after my gran and aunt, they were 'boarded out' with a loving family on the Isle of Arran, and led long and happy lives, my aunt just dying last year at the age of 99. I have copies of the birth certificates which I would be happy to send you. We were aware that my gran and aunt had a half brother through Patrick Kerrigan, but no knowledge of any other family through Annie.
I hope that doesn't come as too much of a shock to you, but the information you have supplied about Hugh has certainly put a few pieces of the puzzle in place for us.
I'm only one day into my research, but it's already been quite fruitful!
