I found ‘Genealogy as Immanent Critique: Working from the Inside’ by Robert Guay at PhilPapers Unpublished Papers Section. It will be published in The Edinburgh Critical History of Philosophy, Vol. IV, edited by Alison Stone.
Nietzsche is the focus of the article, but it looks at the idea of genealogy in a comprehensive way with reference to Rousseau, Kant, Hegel, Mill, Marx, Adorno and Foucault as well. Guay suggests that the idea of genealogy (evolution of concepts) is not distinctive in Nietzsche, but his critical use is, Nietzsche does regard historical development as justification, so his genealogical explanations of moral terms, and other concepts is highly critical.
