My late mother was Margaret Langtry Allan, born 1913 in Glasgow.Curiously, her hame appears as Langtry-Allan on my birth certificate. Her father was William Bloomer Allan born c. 1880 who married Ellen Gray.They also had a son, my uncle, Archibald born c.1915. My great grandfather was Archibald Allan born c.1850 and he married Mary Bloomer.
That's as far back as I can go..My mother always maintained that she was decended from th Langtry line, but I can find no trace of this.She also spoke of her grandmother being Lady ????,but again I have no solid proof of this.
If anyone knows of the Allan - Langtry connection, I would be interested to know.
