Junius Booth's child William

[Saragouzou]

I'm curious to know more about Junius Brutus Booth Sr's son William. I found this on a Wikipedia and wonder why there isn't more information on William. This is what information I have found: (taken from Wikipedia.)

On 26 September 1811, a single woman named Sarah Blackbeard, of St Leonard, Shoreditch, gave birth to a son, William. Called before a magistrate in March 1812, she stated that "one Junius Brutus Booth who resides at his Father's No. 1 Dove Row in the said Parish of St Leonard Shoreditch Gentleman... is the true and only Father of such Child."[2] She repeated this as sworn evidence in 1813, when the child became chargeable on the parish under the Poor Law, giving Booth's address then as Queen Street, Bloomsbury.[3]

I know this website is not that reliable but does this have any truth to it? I'd like to know more about the child, William. Thanks!
