Oh dear.That went of its own accord and before I'd finished.
I have been revisiting the 1901 census:Where is Phyllis? At 6 years old she could be at her grandparents' ,whose names I don't
know,but her maternal grandparents could be Edwards and potentially still at Glan Conway.Alternatively if not with relatives or
friends she could be in hospital.Alternatively as you say she may not be born just yet.
I have found three Phyllis Williams close together born in Llandudno:1893,1894 and 1901(July,Aug,Sep) and therefore after the night of the census.The information for 1894 is not from an original certificate,but has parents as John and Anne nee Edwards and John as master stone mason at Lwynon Gardens and I found John in Slater's Directory 1895 as such with this address.
Gladys is difficult to trace as there are quite a few.
The boys however have quite unique names.From trawling free BMD and NW bmd.John Owen Tudno was born 1898(a,m,j)
and Caradog at 11 months in 1901 can only be Caradog Roland born afterthe census taken on March 31st in 1901(a,m,j)and links strongly with 1911 at Alexandra Road.My mother was only given names John and Roland.However she could not remember having been told of Adelaide Nellie.
I hope your contact may be able to help with these matters.I shall go to the library next week and see if I can find Phyllis in 1901.
If she was on holiday I shan't have much luck!
I saw that Llandudno had a big parade today .I hope the weather was fine for it.
