Searching for information to solidify my knowledge on this family line and be able to work my way back.

Lissy Auguste Dora Meyer (Auguste Dora Lissy Meyer might be the birth name, not certain of the order), born 16 August 1895 in Hamburg, Germany (possibly Ochsenwerder, Hamburg, Germany) to Heinrich August Meyer and Auguste Louise Wilhelmine Lauenburg.
