You go ahead and start whatever threads you like. The field of history I find most fascinating is what is now called "social history" - the study of the actions, thoughts and beliefs of ordinary people.
Too often, history becomes too concerned about the big ticket stuff and forgets the people involved. An example of this is the revisionist history around slavery, with historical figures becoming "cancelled" or reviled. That is unfair. Famous historical figures were men and women of their time and probably didn't give two hoots about the issue. This was because nobody cared. It went on, it might have been disapproved of by people, but it went on and because it didn't affect their lives, they didn't care. That doesn't make them bad people, they were people of their time. It's grossly unfair to judge long-dead people by todays moral standards.
Similarly, Royal or noble or Upper class marriages. These were often political and loveless. Once the poor unfortunately couple had produced an heir and a spare or two, they were effectively free to do as they pleased with who they liked, as long as they were discreet about it and kept up appearances. This attitude changed with King George III and Queen Charlotte, who did fall in love and were faithful to each other their entire adult lives. This was despite theirs being an arranged, political marriage and them meeting for the first time on their wedding day.
What I find more interesting is how it was that Mrs Mary Ross managed to run a successful shipbuilding enterprise on being widowed in a male-dominated world. How did she make a sprawling Government department like the Navy Board take her seriously when tendering for contracts for new warships for the Royal Navy in a field riddled with corruption and nepotism. Let's not forget that Mrs Ross was not the only female shipyard owner in our County. Mrs Frances Barnard successfully ran one of the world's largest shipyards at more or less the same time.
So, yes, write your posts from memory. Detail your childhood and early adulthood experiences. If you don't, they will be lost forever. In 50 years time, we might all be cast as evil because we sat back and tolerated the mass slaughter of sentient beings for meat. Something we don't think twice about now when we munch on a bacon sarnie, much as our ancestors bought a pound of sugar 200 years ago without thinking of how and by whom it was produced.
