A change of plan which will make our lives much easier.
I am in the library where I can access Find my Past. So here it is straight from the Llandegfan Parish Registers:
Llandegfan church, 24 September 1893, baptised Rosetta, daughter of John and Margaret Jones. Abode: Tan y Fonwent. Occupation: labourer.
The spelling of the abode is as per the register entry.
The other children were baptised as follows:
28 September 1879, Zachariah, son of John and Margaret Jones. Abode: Rallt. Occupation: Police Officer.
29 July 1881, Thomas Llewelyn, son of John and Margaret Jones, Abode: ---chester. Occupation: Police Officer. Abode looks like Manchester but it is difficult to read the first 3 letters.
1882 (no date but pre 16 April 1882 as that is the next entry) John Jones, son of John and Margaret Jones, abode: Beudy newydd, occupation: Labourer.
23 November 1884, John Theophilus, illeg, son of John Jones, abode: Tanyfonwent, occupation: Labourer and Phoebe Roberts, abode: Clorobras (

). In the entry, the names of John and Margaret were entered, then Margaret's name crossed out. In the section where the name of John Theophilus is entered, "illeg" has been written underneath the names.
14 March 1886, Frederick, son of John and Margaret Jones, Abode: Tanyfonwent. Occupation: Labourer.
3 May 1891, Alfred, son of John and Margaret Jones, note states, "3 years old". Abode: Tanyfynwent, occupation: Parish Clerk which has been crossed out. On the same day, they baptised Eleazer, son of John and Margaret Jones, Tanyfynwent, occupation: Parish Clerk, again this has been crossed out. There are some letters written underneath but it is impossible to decipher these.
Eleazer Jones was buried in Llandegfan on 29 October 1925, abode: Tanyfynwent, age 34 years. His name is spelt Eleazer in the registers.
There is a burial on 15 November 1893 for Margaret Jones, abode Tanyfonwent, age 37 years.
There is a marriage for John Jones, senior, as follows:
29 January 1901, John Jones, widower, age 45, occupation: Parish Clerk, abode: Tanyfonwent, father: Zachariah Jones, occupation: Fuller. Mary Ann Williams, spinster, age 42, abode: Tanywern, father David Williams, occupation: Gardener. The witnesses were: John Williams and Hannah Jones.
This has answered some questions but thrown up others

One strange matter is that the only baptism I can find for John Jones bc1855, is on 9 May 1856, when John Jones was baptised, son of Henry and Jane Jones, abode: Dauglawdd, occupation: labourer.
It would be a good idea to do a search of the Llandegfan registers to see if there are any more children but I will leave that to another day.
Helig.
