I have Frederick Albert Rowland and his wife Elizabeth based census records from 1881 onwards. I also have a baptism record for their child, Frederick Charles, though they also had 2 more, Herbert and Gordon, and also had an adopted daughter, Ethel Piercey.
Frederick A Rowland's details so far are:
Birth 18 Aug 1850 in Southwark, London, England
Death Jan 1908 in London, United Kingdom
Elizabeth's details are limited to being born around 1854, in Covent Garden, or St Martin in the field, or Strand, based on different census records. Also, in the baptism record of Frederick Charles Rowland, it shows her name to be Elizabeth Lascelles Rowland.
But I'm having trouble finding Frederick or Elizabeth's families in the earlier census records, or even locating a marriage record for him and Elizabeth, with any strong connection.
The closest match I've seen so far is a Frederick Rowland marrying Elizabeth Williamson, listed in the Apr-May-Jun 1877, Strand, London, based on the location and year being just prior to their first son Frederick Charles Rowland birth. This would probably make her the Elizabeth Williamson, daughter of Isaac and Elizabeth Williamson who came from Scotland initially as seen in the 1861 census. But I don't see the Lascelles connection. Trying to find Elizabeth Lascelles as either a middle or surname doesn't seem to find anything concrete either.
If someone could have a quick go at finding something a bit more concrete perhaps via alternative sources, I'd appreciate it.
