I am a descendant of Priscilla Gard of Bridport Dorset. She married William Geoghegan of Scarborough Yorkshire in June 1849 in Sydney Australia. They settled in Kiama.
I am working on the lines of Gards which seem to run close but not the same as you have here and my research appears to conflict on occasions with the detail you list. Perhaps we can sort this out together.
The Australian death certificate says her father was William Gard and her mother Elizabeth Whittle. However thios conflicts with the details in UK. The explanation is that her uncle was William.
Priscilla Gard was baptised at St Swithuns Allington May 30th 1830. Allington is a parish adjacent to Bridport. Her parents were James and Elizabeth GARD who lived in Allington when she was baptised and her father was employed as a mason. She had a brother and four sisters. At the baptism of each the details remain the same: James and Elizabeth GARD Abode Allington Occupation mason. Interestingly, there was another GARD family in Allington at the same time. The parents names were Edward and Hannah. Edward was also a mason.

The Bastard family of Blandford, architects and builders, would have been a great employer of masons as they rebuilt large sections of the town after the great fire of 1731, and it is very possible that the GARD family had worked for them.
The following record appears in the marriage register: James GUARD Batchelor of this parish and Elizabeth WHITTLE spinster of this parish married by banns in Allington St Swithins 11 May 1817. He signed his name and she made her mark. She was a local girl, the daughter of Benjamin and Ann Whittle, baptised in St Swithuns Allington on 17th October 1790. She had a brother William who became a weaver who was baptised in the same church on 15th April 1792.
A search of the local census records has uncovered two more GARD familes: both lived in Bridport at the 1841 census and gave their occupation as Mason. It is possible that all these families are linked and that they came to Bridport in the early 1800's to work on the hard Bothenhampton stone that was quarried to make many of the major buildings in Bridport such as the Union Workhouse and the Rope Mills.
The 1841 census households are as follows: Allington: BetsyGARD 50Spinner Charlotte20Dressmaker Priscilla11 Elizabeth60
Both John and David appear in 1851 census. David is on Portland, the peninsular south of Weymouth, aged 57, and gives his birthplace as Barwick in South Somerset. John is in Bradpole, another parish adjacent to Bridport, aged 61. He gives his birthplace as High Ham in Somerset. Another link to High Ham is the baptism of Truffena Lavis to Ann GARD spinster of Allington at St Swithuns ChurchNov 8th 1822. The name Lavis does not appear in the Bridport Area but there are three Lavis entries in the High Ham trade directory for 1875.
Let us see what we can do with more information as it comes in.
