Before Friedericke Dorothee Westphal (Freda) arrived in Liverpool, Henry Dittmer was lodging with Christian and Sophie Westphal in Everton, Liverpool in 1891. She came to England about 1881.
Her father is recorded as Christian Westphal, a sugar refiner on her marriage certificate of 1892. However, the lack of a DNA connection to WESTPAHL from Bremen, it is possible she was adopted or otherwise taken in by her father for an arranged marriage to Henry Dittmer. However, there is a DNA connection to Delmenhorst by Bremen!
When Freda’s father married in 1888 he was already 41, a sugar refiner and a “bachelor”, not a widower, so Freda may be “Friederike Wilhelmine Dorothee Siegener Klein”, christened 21 Dec 1875 at Bremen, the illegitimate daughter of Louise Elise Marie Siegener Klein. There are three other Bremen birth records with parents Friederike Louise Kleine (or Friederike Keine) and Christian Friedrich Westphahl, but none for Friedericke.
Freda arrived in the UK about 1881-82 but wasn't on the 1891 census, so may have returned with Henry to introduce her to his sister in Germany that year, before they were married, but I cant find any Immigration record on Ancestry.co.uk. Her father however was in Liverpool in 1891.
Married Henry (28-Feb-1892) in Liverpool, Lancashire while living a 2 Gt Nelson Street. Freda used to work in service in a Big House in Liverpool when she was first married.
Fred also worked part-time as a carer for Mrs Lindley, a cripple in a wheel-chair, at Cottingly Cliff, Bingley. She was a smart, thin lady. Her husband was some form of business man.
She (and Henry) were recorded as German subjects on the 1901 census, and later, during WW2, there was concern in the family that they may be interned for the duration of the war.
In 1911, "Fridericka" and Henry (42 & 41) had been married 19 years and were living at 56 Mossman Street, Windhill, Shipley with son Harry (18), born Liverpool.
