Unfortunately, the marriage record of Morris and Matilda Lyons does not survive in the records from Glasgow and likewise the birth records of all their 6 Glasgow-born children (2 boys and 4 girls). I have the marriage records of the two sons, Isidore and Gustavus, but their mother's family name is not recorded. The four daughters never married. All the death certificates, obituaries and gravestone information I have, so far, do not show Matilda's name.
Morris and Matilda became British Subjects between 1861 and 1871 and there should be a record of this available which might show more information. This is my next pursuit! Of course, it is possible that Morris and Matilda were married in Hamburg before they set out for Glasgow and so a records search there is needed.
Thanks for your interest,
