Seigfrid married Anne WELLBURN, from Sunderland, in St. Mary's RC church in 1862. All their children were baptised Catholics and named Klingele. However, they seem to have all chosen to change their family name to Clingly and most also changed from Catholic to Church of England - or at least to allow their children to.
Seigfrid and Anne's children
Seigfrid Albert b.1865
John Thomas b.1872 (Family now in South Australia)
Edwin b.1873 (Family now in Sunderland and USA)
and William b.1875 (Family now in Sunderland)
So far, I have only been able to find present-day families for John Thomas, Edwin and, of course, William - my grandfather. There is a possibility that the eldest son, Seigfrid Albert, had a daughter called Eugenie but I have found no records of this yet.
Seigfrid Albert's details, and those of the girls in the family, are proving to be elusive...
