How to append text and numbers into a title

I am trying to get the title to a plot on two lines, with the first line being a string, and the second one being a combination of a string, day number and month name. Following is one of a number of unsuccessful attemps.

start_month=12;
start_day=1;
mth = month(datetime(1, start_month_ISI, 1), 'Name'); % To get the name of the month
title({'C. Beauharnois';'No. of days to first ISI=1 since',+start_day+'mth'});

The title should show up as follows:

1st line: C. Beauharnois

2nd line: No. of days to first ISI=1 since December 1

Tx!

See subtitle

Or use

start_month = 12;
start_day = 1;
mth = month(datetime(1, start_month, 1), 'Name'); % To get the name of the month
title(["C. Beauharnois"; "No. of days to first ISI=1 since " + start_day + " " + mth]);

The solution by @Matt J and by @Voss below are also good, but this one is simpler. It also includes an interesting option (subtitle) as an alternative approach.

start_month=12;
start_day=1;
mth = month(datetime(1, start_month, 1), 'Name'); % To get the name of the month
title({'C. Beauharnois';['No. of days to first ISI=1 since ',mth{1} ' ' num2str(start_day)]});

start_month_ISI=12;
start_day=1;
mth = month(datetime(1, start_month_ISI, 1), 'Name'); % To get the name of the month
title({'C. Beauharnois';sprintf('No. of days to first ISI=1 since %s %d',mth{1},start_day)});

You were so close, but you can't use + to concatenate character vectors, use strings instead.

I changed the single quotes to double quotes, removed an extraneous comma and changed the reference to start_month_ISI to start_month (and added some spaces).

start_month=12;
start_day=1;
mth = month(datetime(1, start_month, 1), 'Name'); % To get the name of the month
title({"C. Beauharnois";"No. of days to first ISI=1 since " + start_day + " mth"});

Thanks, Les! But that is not quite what I was looking for.
