I found this https://en.wikipedia.org/wiki/Amelia_(1795_ship) which may be that ship and it's indicated it may have been a slaver and is in the ballpark of the right time period.

Ironically there was an HMS Amelia that was first used to defend slavery and then used to uphold abolishment of the slave trade https://yarmouthmuseums.wordpress.com/2021/06/15/the-hms-ame...
