Hello, all.
I have a somewhat difficult English construct that I am trying to figure out how best to render into Irish. The expression is "having been" followed by a verbal noun/past participle, for example, "having been fed all sorts of lies", or "having been born of a clever wit" or some such. How would such a passage or phrasing be rendered into Irish, as it combines the idea of "having", usually expressed with "ag", and "been", past tense or possibly past habitual (?) of "bí".
Any thoughts/suggestions would be appreciated!

There is neither a form for "having" (i.e. a progressive/gerund form of a verb 'to have' or of the verb 'to be') nor a perfect participle / verbal adjective of the verb bí ("been" in English)

English "having been done by me" is present perfect progressive passive.
This could be rendered in Irish by using a so-called mixed perfect (tar éis + bheith + verbal adjective:
Tá sé tar éis bheith déanta agam, It has been done by me, lit. "It is after being made by me"

Edit:
David W. argued in an e-mail that a pronoun is necesassary without the "tá sé ..." part. That's correct.
So: tar éis é a bheith déanta , (it) having been done.

But he is also right in saying that such constructions are stilted.

So if the proposed "tar éis é a bheith" construct would be considered "stilted", how might such an expression from English be rendered more appropriately?

The specific bphrase I am interested in is "...having been born"....

I'd need a full sentence, because it can be translated in many ways, depending on the context.
For instance:

Having been born and brought up in the Gaeltacht I have spoken Irish from the cradle:
do rugadh agus do tógadh sa Ghaelthacht me, agus mar sin tá an Ghaelainn agam ón gcliabhán. (West Cork Irish) ; rugadh agus tógadh sa Ghaeltacht mé, mar sin tá Gaeilg agam ón chliabhán (Donegal)

Also if you mean "since I was born..." you can also say "ó tharla gur rugadh mé..."

Agus an oiread sin déanta agam
Having done all that...
Agus gach uile shórt bréag ráite liom
Having been told all kinds of lies...

I still don't understand English gerunds (not "progressives" as I called them erroneously) very well, so I'm of no help translating them.
