I too have Mullender's from Lowestoft area. Mine were Lavinia Mullender born 1871 at Kirkley who married Thomas Spurgeon Barber from Lowestoft and lived at 'Aston Villa' Rochester Road, Lowestoft. According to 1881 census Lavinia's parents were William E Mullender and Mary Ann Mullender nee ? They lived at Pakefield St. Cottage, Kirkley and had Catherine age 21 born at Kessingland, Suffolk Henry age 20 born Kirkley Esther age 19 born Kirkley Lavinia age 10 born Kirkley Arthur Edward age 8 born Kirkley.
However I'm confused as William was supposed to be born 1832 to a William Mullender and Mary Ann of Pakefield and had brother Daniel born 1846 amongst others all listed on familysearch site. I have some knowledge on my Barber side as my grans's cousin wrote a book called 'hello My Boy Arthur' which is about the Barber family of Lowestoft and Lavinia Mullender who was my gg grandmother. Lavinia was a school teacher before marrying Thomas Spurgeon Barber and she died in 1945.
Does anyone know this family? Please get in touch if you can help. I live in Scotland and so am not even sure about what records are available for the area.
