Hi again, only just found this reply, sorry for the delay! I only recently worked out that William had been married before, so don't have too much on Spicer's branch. William was a harnessmaker/saddler and a number of his children followed him into this business. He was originally from East Chinnock in Somerset, and 5 of his 8 children with 1st wife Eleanor Petwin were born there. Sometime between 1788 and 1790 the family relocated to Southampton as Eleanor had twin sons there in January 1790, both of whom sadly died when only 2 months old. Eleanor had a further son in January 1794 but he also died at 2 months. Of the 8 children (all boys!) born to William and Eleanor I have only found 2 who survived to adulthood, Spicer and Joseph, however I have yet to trace the 2 eldest sons, Thomas and Edward. Joseph became a painter/glazier.
Spicer had 8 children with Mary. 3 died young, but the rest survived to marry and have their own families. Mary Ann's brother John James died on the Isle of Wight in 1838 at the age of 25 leaving a widow and 3 young children. Her brother Joseph was widowed in 1849 with 2 children - his son William is visiting with the Welsteads in the 1851 census. Sister Sarah Jane married James Leach in 1842. There is a possibility that James may be the son of Spicer's brother Thomas, but that is yet to be confirmed. The final brother Thomas is difficult to pin down as there are a few possibilities in the area and needs more investigation.
Do you know which death applies to Mary Ann - I haven't been able to work out which Mary Ann died when.
That's about all I have on this branch at the moment, hope it gives you some more info.
Linda
