Did Thatcher have a wife? Or did he just pay Mrs Kane...
... $50,000 per year to take her young boy under his wing? As a single man?
What was Charles' relationship with Leland? Does the film hint at anything further than just being "good pals"?
Rich single men love to adopt little boys. Look at Dfif'rent Strokes.
Are you asking if the film hinted Charles and Leland were gay lovers? I've never noticed any such hints.
And "Batman". Yes, wealthy bachelors love to adopt little boys!
Seriously, the odds are that Thatcher was married, or had been at some point, a 19th century professional man was expected to marry and live as an exemplary middle-class family man. She may have died comparatively young, or maybe she was just never important enough to Kane to rate a mention in the script, but I've always vaguely assumed there were no Thatcher children. If there had been, then Kane wouldn't have felt so isolated as a child. And seriously, I don't get any kind of creepy vibe from the relationship, just the commonplace resentment an egotistical and entitled man feels for anyone who tries to tell him what to do, a resentment that's particularly strong if the authority figure is right about anything.
