Could you clarify that a bit more Artemisia? If as you say the wife of a cousin comes before the actual cousin then in theory that would mean the Duchess of Gloucester, as a wife, has precedence over her own husband, the actual cousin of the monarch. Alexandra is a male line descendent of a monarch while Patricia Harewood is the window of a female line cousin of a monarch. Did the late Lord Harewood have precedence over Alexandra, although even if he did it likely never happened in practice?
Firstly, there are two different lists - female and male - which are separate and do not intersect with each other. The Duchess of Gloucester takes her ranking from her husband so obviously she doesn't outrank him. The Earl of Harewood didn't have a precedence over Alexandra because they belonged to different precedence lists. On the other hand, the late Earl of Harewood - as female-line descendant - came after the Queen's male-line cousins in the Men's precedence list.
In male Order of Precedence, Sovereign's male cousins are ranked lowest, based rules of primogeniture (which means male-line descendants come ahead of female-line ones). In female Order of Precedence, wives of Sovereign's cousins come ahead of (female) cousins of the Sovereign.
If you think about it, it's no different to, say, autumn and Zara: the latter outranks the former as wife of the Queen's grandson, despite Zara being the Queen's granddaughter herself.
Below are both orders, based on relation to the Sovereign.
