Izzy,
Though I was looking at William I know that Antonio Rossini Clingan, his brother was killed during WWI.
However, it would appear that he was married and had at least one son named after him. I have no details of this marriage but will see what I can find - unless you have details.
I have just found this entry of entry to the USA where it appears the son emigrated to. It might be of interest to you.
Regards
Ian
