There is no evidence they were.
And since Alexandra was married in 1875, its even less likely they were. There would have been some evidence of a divorce from the Grand Duke even if a morgantic marriage.
Alexandra and her son gained their titles through San Marino as Alexander II refused to recognize his son's natural child in any way. Alexei would late gain his Russian title when his Uncle became Emperor.
Beyond his title Alexei does seem to have been accepted by his father's family. He worked in the service of his Uncle Grand Duke Serge, and even married his first wife at Serge's estate.
