I see Grace's father had a high position in the area of a clerk. I couldn't find mention of the occupation of Thomas but I doubt the father would allow his daughter to marry a labourer..
Surnames starting with "Dod" go back to the invasion of England and a man named "Dodda". A son of Dodda would be dods +the word worth = "enclosure" (The Enclosure belonging to the son of Dodda).
The history of the surname Dodsworth and especially somebody with a family name that has been passed down the ages, such as: "Thomas Dodsworth" is interesting :- "When Thomas Dodsworth was born in 1365, in Yorkshire, England, his father, Sir John Clervaux, was 17 and his mother, Beatrix Mauleverer, was 20. He married Agnes Thoresby in 1415, in Thornton Watlass, Yorkshire, England. They were the parents of at least 1 son and 1 daughte"
Apparently the surname "Hostler" is a southern England surname and surfing showed that it was most common in Norfolk and suffolk on the east coast of England. I have an ancestor who was born in the south and moved around because she worked for the Duke of Norfolk as a servant until she married in Hanover Square, London, Middlesex. As with most pregnant wives, she made her way back up north to have her first baby in the presence of her mother in Yorkshire. Once a bride knew what to do to deliver a baby she had the later babies in the home she had made with her husband. Maybe your bride journeyed to have her first baby delivered by her own mother.
I would be asking why the old man needed another wife. did he have young children to look after and as most men in those days had no idea of how to cook, etc., presumably he needed a younger woman to look after his younger children(?) His young wife obviously had a paramour, maybe her husband knew all about him. Did the husband own property, did he leave a will . Widows in the country would have worked on a farm gathering in the harvest, did she take in sewing, or did she take in dirtylaundry to feed her children?
