Personal note from Lucy and Cooper

Thank you so much for everyone's love and support during this difficult time. Losing Clare has been sad, but it's been made a little easier by the support of our community of friends, family and colleagues.

Thank for your generous donations to the charities of Clare's choice, to those who were able to contribute. Clare was a generous philanthropist who donated to numerous charities and non-profits supporting humanitarian aid and environmental causes. We are grateful to those who were able to help continue this legacy in her name.

The memorial and book launch are just over a month away. We look forward to sharing memories of Clare and celebrating her life and legacy in her garden. If you are able to attend either virtually or in-person, please RSVP on this memorial website. We will set up a live stream of the memorial for people to join in from afar. Please RSVP for that so we have your email address if we need it.
If anyone would like to speak at the memorial, please let us know so we can print your name in the program. However there will be time for people to give more casual talks at the event as well.
If you know anyone who knew Clare or was a colleague or friend, please feel free to share the link for the memorial website.
Looking forward to seeing many of you at Clare's memorial garden party on May 17th and at her book launch on May 20.
Best wishes and lots of love, Lucy and Cooper
