Re that Patrick Egan/Julia Welch birth

4 Midford Place
John Egan 60 yrs
Margaret 58 yrs
Patt Egan 19 yrs Son
All born Limerick
Patrick Egan and Julia Welsh are on the same page for a marriage in 1873 , Westminster
SS - you are quoting two different addresses - Southampton Place and Southampton Court
Added
There are deaths for Julia and Jeremiah Egan in 1879.
There may be a connection for John Egan and Timothy/Edward but this information not yet helping.
There is only one birth for Bridget Egan that I can see and that is the one posted with mother Welsh.
Maybe Timothy/Edward and Margaret did not register their children?
Maybe there is a connection to the other Egan family in Midford Place.
We are back to information on certificates.
Marriage of Timothy to Margaret Mannix - name of his father etc
Marriage of Patrick to Julia Welsh - name of his father etc.
Children in 1881 with mmn Welsh
Bridget
Margaret
Mary
I can’t see a birth for Timothy abt 1873 - nor the older boys as previously mentioned.
Julia Welsh Egan died - maybe the children were raised by Timothy?
Again, certificates perhaps.
