Dear Marie,
I have just noticed that you do not have my g grandmother listed as one of Alexander Todd's children. Margaret was born 1857 Douglas, references 1861 IOM census, 1871 IOM census she is recorded as Maggie Todd. I also found her immigration records, mother Sarah living in Isle of Man, father Alexander gardener deceased. Her death certificate also carries Alexander's name and occupation. Let me know if you are interested in any of these records
Regards,
Denise Larcombe (nee Kermode)
