It looks like the sentence you have submitted is “he was came of on 7th may 1861”. It is not correct for two reasons.
The first mistake is the verb. You have “was came of” in the sentence, but this does not make sense. What are you trying to say?
You have two different past tense verbs (was and came) right next to each other. We almost never write like this. Assuming that your verb is supposed to be “came of”, I am also confused. Of is not a common preposition that follows came.
The right phrasal verbs are usually came to (meaning awakening or coming out of a coma), came out (meaning to go out of something), and came off (meaning the way that other people perceive you). These possibilities might be more appropriate, but it is hard to tell which one you mean because there is no context for this sentence.
The second mistake is the date. Depending on the audience that you are writing this for, the format of the date might be incorrect. Regardless of where you are, you should put a comma (,) after the day and month, and before the year.
In the UK, you would put the day first, just like you did. Whether you put the numerical designation (the “th”) is up to you. That is not necessary, but is not wrong. However, if you are writing for an American audience, you should put the month before the day, like this:
- May 7th, 1861
Hope this clarifies things for you!
