This edition would not have been possible without the guidance, expertise, and encouragement of many people (all remaining errors are, of course, my own). The origins of this edition stem from my PhD research at the University of Sheffield, funded by an AHRC scholarship. I owe my thanks to my PhD supervisors Graham Williams and Susan Fitzmaurice, and my PhD examiners, Alison Wiggins and Jane Hodson.

Two fellowships – a Postdoctoral Fellowship from the Society of Renaissance Studies, and a Marie Skłodowska-Curie Actions Postdoctoral Fellowship (ref: 101064348) – provided the vital time and resources that I needed to complete this edition.

Numerous people have provided important guidance and advice which has helped in the development of this edition. This includes Jade Scott, Jeremy Smith, Joanna Kopaczyk, Joseph Massey, Bryony Coombs, Lucy Dean, Emily Wingfield, and Steve Murdoch, who willingly answered my odd queries on all things related to Scots language and letters, and Scottish history and archives. Alan Bryson provided advice on where to find Margaret Tudor's letters in the first place. Samuli Kaislaniemi, Carlo M. Bajetta, and Guillame Coatalen were ever ready to answer questions on early modern royal correspondence. Ellie Woodacre and Amber Regis provided helpful advice and encouragement on how I might go about developing the edition. Christine Wallis was always willing to discuss the peculiarities of historical linguistics and editorial practice. The members of Aston University's History Colloquium also provided helpful feedback and encouragement on the first drafts of the edition. Finally, the ‘Editing Early Modern Women's Letters’ symposium hosted by Ann-Maria Walsh and Ramona Wray at Queen’s University Belfast in June 2022, provided the much-needed confidence boost and encouragement I needed to finish the edition.

My especial thanks goes to Amy Hayes and Mel Evans for their encouragement, support, and friendship. Amy's expertise in medieval Scottish queenship, and enthusiasm for Margaret Tudor, was crucial to the development of this edition. Mel also provided vital expertise in historical linguistics and royal correspondence, as well as helpful and insightful feedback on the final draft of the edition.

Thank you to Danielle Clarke for her mentorship, encouragement, and feedback on the edition. I am also grateful to Tim Grant for always taking the time (in an incredibly busy schedule) to give me the vital encouragement and mentorship that I needed to finish the edition. Thank you to my editors Siobhan Talbott and Andrew Spicer at the Camden Fifth Series for all of their help in developing this edition. I am also grateful to the anonymous reviewers who provided helpful feedback on earlier drafts of the edition, as well as to Jem Langworthy for meticulous copy-editing of a challenging edition.

I am particularly grateful to The National Archives, The British Library, and The Bodleian Library for granting me access to the manuscript materials and for their permission to print my transcriptions of Margaret Tudor's letters held in their archives. I also owe thanks to the staff of these institutions (in particular, Andrea Clarke, Neil Johnston, and Julian Harrison) for their help and advice.

Thank you to my family for their support, encouragement, and for putting up with me talking about Margaret Tudor for the last decade. Finally, thank you to my husband, Ben, for encouraging me in the final stages of writing the edition, for adding many commas, and for making the map.
