I should also have mentioned that Anglo-Saxon letter 'ȝ', 'yogh', (or 'ȝoȝ'), which originated in the Latin minuscule 'g'. After the arrival of further missionaries from the Vatican during the 900s, the letters 'ȝ' and 'g' became distinct. Again, the Normans were not overly enamoured with this uniquely English letter, and replaced it entirely with either 'g', 'gh' or 'y' (as in 'berg', 'night' and 'yesterday' respectively).
Despite having gone from English by the early 1200s, yogh did survive for considerably longer in the Scots language, spoken in much of southern Scotland. This continued until the arrival of the printing press, when English printers, wishing to print texts in Scots, found that they did not have a type for 'ȝ', replaced it instead with 'z', which at the time (1400s) was often written tailed: 'ʒ'.
This is why there are several Scottish surnames containing an oddly pronounced 'z', for example 'Menzies', which is properly pronounced /ˈmɪŋɨs/. In recent times, however, a spelling-influenced pronunciation has arisen, and this has quickly become the norm. Yogh is still occasionally seen in Scots, however: https://sco.wikipedia.org/wiki/Yoch
I hope this was useful and informational.
