You mentioned Kimpton, about five miles north of St Albans. Here are two places, Caldicote and St Paul's Walden, which are within a mile or two of Kimpton.
If you go to the HALS site:
https://www.hertfordshire.gov.uk/services/Libraries-and-archives/Hertfordshire-Archives-and-Local-Studies/Hertfordshire-Archives-and-Local-Studies.aspxAnd Search Hertfordshire Names Online for surname Skypwyth, you will find a will for:
Peter Skypwyth, 1464, who requested to be buried at Codicote.
Codicote is about a mile east of Kimpton.
And here is an earlier Common Pleas record with John Skypwyth. He is not identified further, but this is probably the same person from St Albans:

Herts. John Skypwyth versus John Theyne, of Rugge/Ridge, husbandman; John Sampson, of Tydenhangre/Tyttenhanger, dyer; John Smyth, of Walden Abbots/St Paul’s Walden, husbandman. Debt.
Ridge and Tyttenhanger are both near St Albans; St Paul's Walden is about two miles north of Kimpton.
You can order copies of wills from HALS. In 1464 it will probably be in Latin and not very easy to read, but if you post an image or link here, there are people who can help decipher it.
Wills at that time might be uninformative. Often they include several religious bequests and not much more, but it might be worth a look.
