rjd on Family Tree Circles

Hello out there. We've recently traced our ancestor, Sarah McVeigh back to her homeland of Armagh County, Ireland. Sarah was born in 1830 in Armagh, daughter of Patrick McVeigh and his wife Maryanne nee Hatherton from Armagh. Sarah arrived in Australia aboard the Matoaka-Sultana in 1854, aged 24. She arrived in May 1854, and was married to a James Christopher Egan in Dec 1854. Two sisters travelled with her to Australia aboard the Matoaka; Bridget Egan and Anne Egan..these two girls may well have been the sisters of James, who befriended Sarah on the long journey from Ireland, or may have on the other hand introduced their brother or cousin James to Sarah on arrival. Sarah married very quickly, regardless of the senario. James is known to have come from Dublin..Bridget and Annes's origins are unknown. James and Sarah travelled around Victoria, Australia, where 4 of their 6 children were born in different towns. Their last 2 sons sadly, died as little babies, and Sarah went into a deep Post-natal depression. She was sent to the Yarra Bend Asylum in Victoria (where anyone and everyone was sent in those days). She died there at the age of 35 years,and was buried there. We're seeking anyone who can fill in the sibling line of both Sarah, and her parents Patrick and Maryanne. Any info would be much appreciated. Thankyou very much Aussie rjd.
